This isn't something I'm going to debate with amateurs. Anyway the point is that the color that nitriding turns steel is irrelevant and doesn't affect the material properties even if it's been rubbed off despite what the internet experts would have you believe. Would recommend. One complication to chrome-plating is that it adds to the dimensions of finished parts, so components must be undersize by whatever thickness the plating will add. Posted by Boban Jancevski on Feb 6th 2023. Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. L. Neil Smith. NiB-coated components are relatively easy to clean up but may become discolored when subjected to high heat. Nitride Names like Melonite, Ni-Corr, Black nitride or salt bath nitride are all. The Kasenit procedure is to heat to 1650*F, and roll the part in the material, reheat, repeat if necessary for added depth and quench. Typical applications include gears, crankshafts, camshafts, cam followers, valve parts, extruder screws, die-casting tools, forging dies, extrusion dies, firearm components, injectors and plastic-mold tools.[1]. Usually steels are beneficially treated with plasma nitriding. Most chrome moly barrels that were parkerized in days past are now melonited, which is a fancy name for black nitride. It it the current mil-spec to have a phosphated bolt carrier group with the inside of the gas key and carrier where the bolt rides hard chromed. In the plasma nitriding processes, nitrogen gas (N2) is usually the nitrogen carrying gas. RESULTS: Cleaning was reduced, replacement intervals extended five times thanks to greater longevity gained from using black nitride products. This slide is available for slide swap, which will require you to send in a stripped OEM Gen 3 Glock 19 slide. Heh, Yeah I thought we were going to get some useful info there for a minute "Son" if it makes you feel any better, I didn't see it coming either. It is far cheaper than similar corrosion protection systems, such as paint and electroplating. That all depends on the pre-existing material properties, the cross sectional thickness where exposed to the N2 atmosphere, and the final case depth and hardness. You can also add Nitride treatment and Cerakote products at the same time! Not a fan of using degreasers on firearms. Plasma nitriding, also known as ion nitriding, plasma ion nitridingor glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. Spray-on coatings are best-suited for rifle exteriors where the inevitable variations in thickness will not change tolerances nor impede function. It provides a Rc 55 surface . It calls for no machining, or polishing or any other post-nitriding operations. Depending on performance needs, deposits can include combinations of hardness, wear, abrasion and corrosion resistance, lubricity, solderability, high-temperature performance and protection from various chemicals. currahee1911 Black Nitride adds roughly 3 weeks to your slide order. Black Nitride. Home Rifle and Shotgun Accessories Triggers, Pins Fortis Takedown Pin AR-15 Black Nitride. Looks better than a factory cut. Since the process requires no electrical current, controllable coating deposition rates produce consistent tolerances within 1 to 2 microns. Black nickel is a derivative of nickel boron. Please note: Due to the unique nature of this type of treatment process, slides are sent off to a shop that specializes in this type of refinishing. Such highly active gas with ionized molecules is called plasma, naming the technique. ).You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. Lubes for me run brtween breakfree clp on my old firearms as thats been used on them for up to 40 years and pro-shot one step on the new ones. Fortis Takedown Pin AR-15 Black Nitride $ 21.95. One barrel coated in Cerakote Ceramic Coatings by T. All WMD finishes are applied in a facility that has earned NADCAP accreditationthe highest level of process control recognized in the aerospace industry! When components do not bond correctly (adhesive issues) wear can result as well. We also find chrome in less-obvious places like piston-rod ends, the inside of an ARs bolt carrier and in the open end of the carriers gas key. It provides a Rc 55 surface through a high temperature diffusion process. PROBLEM: Die soldering during casting process was degrading core pin surfaces, which required cleaning three to four times per shift, andreplacement every month. Black nitride is a surface conversion that diffuses into the material, altering the chemical make up for increased hardness, improved strength, and ultimately better durability. Simply add both products to your order! Great service. And you can rest assured that behind-the-scenes work is being done that may well represent a quantum leap in metal surface treatments. Making stainless black is a side effect and even if the color wears away the metallurgical properties are unchanged. Like I said, I do this stuff for a living and my knowledge goes a little beyond what you can find on the internet. No longer will your surgeon be distracted by bright, shiny objects. - MAD Black & MAD Black Plus are also extremely flexible as there was no coating loss at a 180 degree rotation (ASTM D522) - Impact resistance exceeded 160/160 inch-lbs, which is the highest level on the test (ASTM D2794) MAD Black Plus vs. NP3, NP3 Plus, Melonite finishes, TiN, NiB-X and Micro Slick Nitriding is like a low temperature (930 - 1020F) form of carburizing. Today we have much better gun coating options for our ferrous-metal rifle parts. $0.00. Whether one ounce or 4,000 lbs., orders are filled with the precision and quality for which we're recognized. Before getting into the meat and potatoes of these valves, we should discuss what, exactly, the nitriding process is, and how it justifies the extra costs involved. Thats why I and many others choose black nitride. Coating: Nitride. If you are in the market for new AR-15 parts, specifically a bolt carrier group, you might be a little overwhelmed with the various treatments/coatings available today. A forum community dedicated to all firearm owners and enthusiasts. Do NOT ship the lower of the firearm as we are not transferring the firearm. My Glock nor my Sig needed any special attention other than a quick coat of oil & they look as good as new. Rail and high wear areas is pro-shots zero-friction, Some of the BP guys have said they will heat their frames up after a bathing and apply oil to the heated frame. The durability and corrosion protection offered by black nitride treatment is unmatched by any other coating available. But traditional firearm finishes still have their place. You can blacken a number of materials including ferrous materials, stainless steel, copper, copper alloys, zinc, powdered metals, and silver solder. This process isn't really a gun coating, since it doesnt change a parts finished dimensions, so it is well-suited for both precision internal components and bores. But it uses sodium cyanide salt to case harden the part without the normal distortion of heat treating. 172 votes, 80 comments. Thanks for the responses. you use ammonia gas to nitride, not CN, typical application for say a die would be 500-575 degrees for 12-14 hrs, stay away from salt bath hardening if you can, if surface requires cyanide salt hardening go to a heat treatment co, sticking yourself with antidode hurts, but not as much as CN poisoning! That's simply not the case in this application (assuming it's done correctly). These bolt carriers had a natural lubricity and proved to be durable, the only downside beingthat the hard chrome plating was prone to flaking. Systematic investigation into the effect of nitrogen on the surface properties of steel began in the 1920s. All round nitriding effect (can be a disadvantage in some cases, compared with plasma nitriding), Large batch sizes possible - the limiting factor being furnace size and gas flow, With modern computer control of the atmosphere the nitriding results can be closely controlled, Relatively low equipment cost - especially compared with plasma, Reaction kinetics heavily influenced by surface condition - an oily surface or one contaminated with cutting fluids will deliver poor results, Surface activation is sometimes required to treat steels with a high chromium content - compare sputtering during plasma nitriding, Ammonia as nitriding medium - though not especially toxic it is harmful when inhaled at a high concentration.

Returns PolicyYou may return most new, unopened items within 30 days of delivery for a full refund. Well, rhe information seemed useful for a while there, but those last comments kinda lost the audience. After WWII the process was reintroduced from Europe. Items sent in only for black Nitride have a 3-6 week turn around time. NiB reduces friction and speeds the cooling of high-heat components due to the increased surface area created by the coatings texture. You will receive a link to create a new password via email. They have a fair amount of wear resistance, but heavy use or careless handling can still cause them to wear through, scratch or chip off. The customer service was outstanding. Some internet experts are of the opinion that nitriding compromises the material and makes it unsafe. Hot Black Oxide converts the surface into Magnetite. In plasma nitriding, the reactivity of the nitriding media is not due to the temperature but to the gas ionized state. Mar 23, 2014. Core Pin hardness 50-55 HRC, comes complete with finished detail. So, you have ignored the question. All times are GMT-5. In a word: Rust. Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. Outstanding job! Salt Bath Nitriding (DHSN) Salt Bath Nitriding/Nitrocarburizing was originally created as an alternative to gas nitriding that would produce a more uniform case through surface contact between the substrate and liquid salt. For the nitriding process H2 gas is also added to keep the surface clear of oxides. Were confident that our NiB-X coating provides the optimal combination of hardness, wear resistance, lubricity, and corrosion resistance. Superb Job!!!!!!!!! Hard (harder than carbide, 3X hard chrome) Inert and stable material. As such, we are unable to guarantee specific turnaround or lead times for this service, although in our experience the vendor we use has been very good with their quoted times. Second slide they have coated for me. But, those firearms were too shiny for my liking (and out of my price range anyway). WMD Guns will coat pistols, rifles (ARs, bolt actions, semi-automatics) and shotguns. Internal rifle components appear to be the best-suited for NiB, and in my experience, this gun coating is much more durable than traditional plated finishes on contact surfaces like bolt-locking lugs. Black Nitride Slide Coating. The DS9 Limited Optics Competition Pistol was designed with heavy influence from our Team MPA members, which includes some of top Shooters in the USPSA. PlatedReflective, plated finishes such as hard chrome, nickel and gold have been around longer than anyone presently reading this magazine. The physical vapour deposition techniques are widely used to deposit a wide range of materials on a number of base . More durable thancerakoteor bluing. The black nitride treatmentis very durable and highly resistant to wear and it will not flake because it is not a coating. A few years ago there were only two options, phosphate or a hard chrome. Thats really not an accurate statement. Kalamazoo MI, 49009When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. The blacking process creates a layer about 1 m thick. For fun I compared the finish from two Brownells cold bluing products: Dicropan T-4 and Oxpho-Blue Creme Cold Bluing Test. BlackNitride! Received my P320 slide and the finish exceeded my expectations! The key to our engineered nickel boron plating processes is versatility. By the way, I asked in the Tailstock thread (where John first suggested Nitriding the tailstock ram) whether you need special steel to nitride. Nitriding of stainless is also redundant, and . Most tactical-rifle shooters have experience with chrome-lined bores, which provide wear- and corrosion-resistance. [2] When ammonia comes into contact with the heated work piece it dissociates into nitrogen and hydrogen. Plasma nitriding can thus be performed in a broad temperature range, from 260C to more than 600C. The advantages of gas nitriding over other variants are: In salt bath nitriding the nitrogen donating medium is a nitrogen-containing salt such as cyanide salt. So nobody should send a gun out for nitriding? Precise control of chemical potential of nitrogen in the nitriding atmosphere by controlling gas flow rate of nitrogen and oxygen. Calico Titanium Nitride (TiN) the staple of thin film coating solves tribological problems with machine components that can be coated at temperatures of 425C - 450C. There are hot plasmas typified by plasma jets used for metal cutting, welding, cladding or spraying. I would like them to do rifle barrels too. You can post now and register later. I had a 1911 done last year by Primary Machine. Solving metal problems for over 70 years. The treatment results in a deep jet-black color compared to our Black DLC (PVD) coating which is a dark "smokey black" color. Ideally, steels for nitriding should be in the hardened and tempered condition, requiring nitriding to take place at a lower temperature than the last tempering temperature. The cost is pretty reasonable. Specialized treatment outlasts conventional leader pins and bushings. These processes are most commonly used on low-alloy steels. Our NiB-X coatings are certified to ASTMB607 and/or AMS2433C. Compatibility: AR-15. So I can say its a pretty good treatments. Bluing and Black Oxides are essentially the same thing. Rubbed in well. The only specifically interesting feature of the ferrocyanide is the N in it. Its a surface treatment which isnot the same as a full heat treat. This process isn't commonly used due to the expense in treating the bolt carrier twice. The application of oil, wax, or lacquer will bring the corrosion resistance up to par with the heated processes. The coating has a Rc 70 and a coefficient of friction of .06. Minimal amounts of material should be removed post nitriding to preserve the surface hardness. The advantages of salt nitriding is that it achieves higher diffusion in the same period of time compared to any other method. The Salt Bath Nitride process is a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change. Our engineered Electroless nickel plating processes can be tailored to provide various levels of hardness, wear, abrasion and corrosion resistance, and lubricity. It removes oils from the pores of the metal and can cause rust easily on tiny internal parts. Free delivery for many products! Nitromet Salt Bath Nitrocarburizing (i.e., Melonite). Black oxide, TiN, TiCN, and TiAlN are the most used coating on metal drill bits. This also helps the thermal stability of the plasma plant, since the heat added by the plasma is already present during the warm up and hence once the process temperature is reached the actual nitriding begins with minor heating changes. From a production standpoint, nitriding is inexpensive and so long as it is done correctly, the high temperatures that the process relies on for application will not harm steel rifle components. If you have an account, sign in now to post with your account. brazenfirearms@gmail.com. Black Nitride is supposed to harden the metal somewhat, and improve lubricity of moving parts. We were cleaning up our guns and he suggested non- chlorinated brake cleaner. 10/10 would recommend. The Cold processes produce a similar color, but the coating tends to rub off more easily and offer less abrasion resistance. There was nothing useful in this thread since everything that had been said here prior was just flat out wrong. When applying, the material is first coated with nickel boron, then it is treated in a salt nitride bath. The Midnight G10 camouflage handle is triple-riveted and built to withstand even the most vigorous slicing, dicing, and cutting. I use the braklean also, just as the previous poster said, use a bit of oil on the exterior, wipe it down and voil! For customers, this means unsurpassed wear protection. You can also add Nitride treatment and Cerakote products at the same time! You cannot paste images directly. Thus the process is user-friendly, saves energy since it works fastest, and causes little or no distortion.

Hot Black Oxide involves hot baths of sodium hydroxide (the nasty stuff in drain cleaner), nitrates, and nitrites. Precision honed lubricious surface that does not require grease. A value-priced red dot with a full set of features. Since nitrogen ions are made available by ionization, differently from gas or salt bath, plasma nitriding efficiency does not depend on the temperature. The process has long since become standard in military and police battle rifles and carbines around the world. The nitrogen then diffuses onto the surface of the material creating a nitride layer. Sophisticated black, non-reflective titanium-nitride coating adds corrosion resistance, toughens the blade and enhances non-stick properties. This process isnt commonly used due to the expense in treating the bolt carrier twice. We will respond quickly with instructions for how to return items from your order. This coating is an electroless nickel with Teflon particles co-deposited within the matrix.

Accordingly, please allow approximately two weeks of additional lead time for your order when purchasing this service. But it uses sodium cyanide salt to case harden the part without the normal distortion of heat treating. Posted by Bobby Freeman on Oct 27th 2022, The nitride finish applied by Maple Leaf Firearms is phenomenal! The Optic fits like a glove. The weight of any such item can be found on its detail page. H&M Blacknitride+ | The New Standard in Steel Hardening Now Available Nationwide! Finish on slide is excellent. Superior wear resistance, and includes particle rings for lubrication retention. CNC machines only go through the motions. Because nitriding involves heating poisonous salts to high temperatures, I don't think it's practical in a home shop. The coating on my slide turned out great. Attempts to chrome-line rifle bores date back to the first half of the 20th century. Less wear & tear and on your rental guns with NiB-X, Higher reliability (fewer stoppages) for customers renting and using range guns, Easier to clean for your employees (wipes clean in most cases), Higher resale value since the NIB-X coated guns show little to no wear, More environmental corrosion protection than blued or stainless steel guns, Very lubricious (CoF .07) and needs little to no lubrication to operate, Less maintenance (longer usage between cleaning cycles), Harder than Tennifer, Melonite, Nickel Teflon and Hard Chrome (NiB-X is Rc72). The thickness and phase constitution of the resulting nitriding layers can be selected and the process optimized for the particular properties required. TiN is a thinly-applied surface coating has a shiny gold-like appearance and is often used for show builds due to aesthetics. Its because WMD offers a full spectrum of firearm-specific coatings, ranging from decorative ceramic topcoats to high-performance proprietary coatings, they include as follows: NiB-X is our proprietary formulationand a remarkable technology that proves that not all nickel boron coatings are created equal. [4] For instance, at moderate temperatures (like 420C), stainless steels can be nitrided without the formation of chromium nitride precipitates and hence maintaining their corrosion resistance properties.[5]. Spray-ons have the added benefit of being equally well-suited for aluminum, polymer and wooden rifle components, too. Items sent in only for black Nitride have a 3-6 week turn around time. We provide options as there are many aftermarket slides with various coatings. Who will finish strong in a corrosion test (ASTM B117) featuring two barrels? While no longer popular on long gun exteriors, surface treatments like chrome-plating work well on and in certain internal components. In this technique intense electric fields are used to generate ionized molecules of the gas around the surface to be nitrided. 4110 I-70 North Outer Road The treatment superficially hardens the surface of the steel as it is IN the steel, unlike a coating that sits on the surface of the steel. Manufactured to withstand pressure of hard-to-align dies with diagonal thermal expansion. The new standard in steel hardening. Your email address will not be published.
