Black Nitride Slide Coating. In "Foundations of Mechanical Accuracy" the Moore boys use Nitralloy, which is an extremely expensive tool steel. The Cold processes produce a similar color, but the coating tends to rub off more easily and offer less abrasion resistance. And you can rest assured that behind-the-scenes work is being done that may well represent a quantum leap in metal surface treatments. Your email address will not be published. I dont know anything about the process, but I do know that I sent my slide to Primary Machinefor some slide work and had the nitride finish done. Upload or insert images from URL. With so little demand the process was largely forgotten in the US. More durable thancerakoteor bluing. There was nothing useful in this thread since everything that had been said here prior was just flat out wrong. Some of the early M16 rifles adopted by the US military had a hard-chromed bolt carrier. Simple operation - heat the salt and workpieces to temperature and submerge until the duration has transpired. The chemicals associated with these treatments convert a surface layer of the steel to magnetite. This way you gain the full benefit of Nitride treatment with the unlimited color and pattern options that Cerakote coating affords! 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. I believe I have damaged the black nitride finish on my new Baretta Nano. This coating withstands higher temperature and pressures better than EN Teflon.The boron nitride particles are a much better choice than Teflon for firearms applications. Even finish with consistent tone and great attention to detail as all the nooks and crannies are finished beautifully! 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. Black Nitride is more than just a baked on coating such as Cerakote (I have nothing against Cerakote, as I have 2 rifles with it). Usually used for release properties in the mold and die industry. Still not as wear resistant as NiB-X but suitable for some wear applications. Bolt-carrier groups above, from left, represent Nickel Boron, phosphate (Palmetto State Armory), Robar NP3, black nitride (Brownells) and chrome-plate (Daniel Defense).Advances in gun coating technology can be wonderful.

In recent years, the firearms field has seen the introduction of revolutionary new metal coatings and surface treatments that deliver unprecedented levels of corrosion protection, wear resistance and reliability. Ok, that's fair. 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. Titanium nitride coating applications are capable of dealing with wear caused by problems involving abrasions and adhesives. The nitriding process actually becomes part of the material being treated . Made from high-quality 416R stainless steel, this barrel features a nitride finish for maximum corrosion resistance, nickel teflon extension for added durability and lubricity, and 5R rifling for excellent accuracy and . Making stainless black is a side effect and even if the color wears away the metallurgical properties are unchanged. The aim of this article was to deliver a review of the tribological properties of nitride-based coatings attained using various techniques including physical vapour deposition, chemical vapour deposition and spraying techniques. A fine-turned or ground surface finish is best. Black Nitride is supposed to harden the metal somewhat, and improve lubricity of moving parts. Our NiB-X coatings are certified to ASTMB607 and/or AMS2433C. This process was invented by Bernhardt Berghaus of Germany who later settled in Zurich to escape Nazi persecution. 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).

These bolt carriers had a natural lubricity and proved to be durable, the only downside beingthat the hard chrome plating was prone to flaking. 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. By High-tech gun coatings such as Robars NP3 and FailZeros Exo Technology boast additional advantages over the coatings described here. So I can say its a pretty good treatments. Coating can be duplexed with sublayers or topcoats to enhance specific properties customers may desire. Because steels with higher alloy contents were not readily available for nitriding, Fry became responsible for developing a group of steels for Krupp known as the "Nitralloy . WMD Guns is no longer offering the Upgrade program for individual parts. Home Rifle and Shotgun Accessories Triggers, Pins Fortis Takedown Pin AR-15 Black Nitride.

Thisarticle, "Any Color You Like," appeared originally as aRifles Column in the July 2017 issue of Shooting Illustrated. Solving metal problems for over 70 years. The Fora platform includes forum software by XenForo. Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. By the way, I asked in the Tailstock thread (where John first suggested Nitriding the tailstock ram) whether you need special steel to nitride. Its a surface treatment which isnot the same as a full heat treat. It is a deposited copper selenium compound. 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. The Optic fits like a glove. Spray-ons have the added benefit of being equally well-suited for aluminum, polymer and wooden rifle components, too. The oldest and most widely used specification for hot black oxide is MIL-DTL-13924, which covers four classes of processes for different substrates.

Nitriding is like a low temperature (930 - 1020F) form of carburizing. brazenfirearms@gmail.com. Maybe it would accept more oil if you heated it GENTLY? An added plus is, unlike chrome liningwhich is mostly limited to chrome-moly steel blendsnitriding is optimal for stainless-steel bores, too. As a Corporate Champion, Dalstrong supports Wounded Warrior Project (WWP) in their effort to deliver life- changing programs to over 100,000 wounded warriors, their families, and caregivers. Ive had it for about a year, thousands of holsterpresentations, and about 7 thousand rounds through it and I can find no wear marks at all. The blacking process creates a layer about 1 m thick. Phosphate is not a surface coating, but a metal treatment that penetrates the metal which reduces friction and prevents corrosion. Most of the [few] commercially available modern sporting rifles and surplus longarms of the day had some form of Parkerized finish. Would recommend. In case you were wondering, this is part of what I do for a living. 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. Recent developments have led to a process that can be accurately controlled. Precision honed lubricious surface that does not require grease. The person sending the gun doesn't have to be an expert if the company doing the finishing is. Hot Black Oxide converts the surface into Magnetite. View a video excerpt from a past Webinar that presents an exclusive Pin and Sleeve combination that delivers great performance for long run cleanroom tooling to harsh die casting applications. This coating is notable because it has all the slickness and ease of cleaning of a nickel boron carrier but the hardness properties of the black nitride making it less prone to flaking. 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. When materials contain non-smooth properties, wear can easily occur. Contact our plant near your facility. When searching for a bolt carrier group to purchase, you will run across NiB or nickel boron. The durability and corrosion protection offered by black nitride treatment is unmatched by any other coating available. 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. 172 votes, 80 comments. Show. 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. Yep - i read that just a little bit ago looks like, if i want to nitride something, i need to get a hold of some chrome-moly. Well, rhe information seemed useful for a while there, but those last comments kinda lost the audience. The weight of any such item can be found on its detail page. Who will finish strong in a corrosion test (ASTM B117) featuring two barrels? As for cosmetics, the wear properties of the surface may be a concernfor some people,even if the underlying metal isn't affected. The finished product was amazing as well!! Black nickel is a derivative of nickel boron. The Faxon Match Series 24" Heavy Fluted 6mm ARC AR-15 Barrel is designed for precision and performance, with a heavy fluted design that reduces weight and enhances performance. I had a 1911 done last year by Primary Machine. Copyright 2023 National Rifle Association. NiB provides excellent corrosion resistance, but over time it will give way to the ravages of high heat and pressure on hard-use components. Bob is also the founder of CNCCookbook, the largest CNC-related blog on the Internet. The temperature used is typical of all nitrocarburizing processes: 550 to 570C.
