These bolt carriers had a natural lubricity and proved to be durable, the only downside beingthat the hard chrome plating was prone to flaking. Both the Dicropan T-4 and the Oxpho-Blue Creme came as creams, which made them easier to apply. The process has long since become standard in military and police battle rifles and carbines around the world. The Basics of Titanium Nitride Coating | A&A Thermal Spray Coatings Some internet experts are of the opinion that nitriding compromises the material and makes it unsafe. [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]. 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. Our Big List of over 200 CNC Tips and Techniques. Definitely would recommend this service. You cannot paste images directly. NiB-coated components are relatively easy to clean up but may become discolored when subjected to high heat.

Superb Job!!!!!!!!! Do this wearing gloves as the chemicals are fairly nasty. Choosing a bolt carrier group can get pretty touchy because everybody has an opinion of which is the better coating or treatment. 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. We trust these pins to perform in the harshest conditions.. Black Nitride adds roughly 3 weeks to your slide order. This treatmentis great for use on barrels to prevent corrosion and increase barrel life. This is by far the most popular and well-known finish to have on a bolt carrier group. You people realize that nitriding is a heat treatment and that its purpose is to change the metallurgy of the steel? SKU: PINS-TDPIV-BLK. Enjoy the comfort of its rugged grip, resistant to both extreme hot and cold temperatures for long-term durability. You do as you wish, I really don't care. 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. By the way, I asked in the Tailstock thread (where John first suggested Nitriding the tailstock ram) whether you need special steel to nitride. Much research has taken place in recent decades to understand the thermodynamics and kinetics of the reactions involved.

WMD Guns is no longer offering the Upgrade program for individual parts. Nickel Boron is a surface coating that is increasingly becoming a favorite among individuals wanting an easier to clean bolt carrier group that hasa natural lubricity. Hard chrome is a surface plating that covers the outside of the carrier. I simply cleaned them in some mineral spirits and then applied the compounds with a folded paper towel. For instance, mechanical properties of austenitic stainless steel like resistance to wear can be significantly augmented and the surface hardness of tool steels can be doubled.[3][4]. Black Nitride products from Progressive are proven to perform in medical cleanroom molding environments, cosmetic/appearance product production, harsh conditions such as die casting, and beyond. Internal components in those days were usually stainless, Parkerized, blued or sometimes left in the white.. Who the hell who send their personal stuff to be nitrided even knows what AMS 2753 and 2759/6 are? Grip Color. As for cosmetics, the wear properties of the surface may be a concern for some people, even if the underlying metal isn't affected. NiB-X nickel boron parts are known for high hardness, good adhesion, excellent lubricity, low coefficient of friction and uniform coverage. Jun 9, 2013. The thickness and phase constitution of the resulting nitriding layers can be selected and the process optimized for the particular properties required. Considering slide and frame work on my 1911. Not AR-15 barrels, but AK barrels, 10/22 barrels, etc. Black Nitride Barrel Coating. When applying, the material is first coated with nickel boron, then it is treated in a salt nitride bath. The durability and corrosion protection offered by black nitride treatment is unmatched by any other coating available. Were confident that our NiB-X coating provides the optimal combination of hardness, wear resistance, lubricity, and corrosion resistance. Bluing and Black Oxides are essentially the same thing. The nitriding was done by an outside vendor. Plasma nitriding can thus be performed in a broad temperature range, from 260C to more than 600C. Black oxide - Wikipedia Still not as wear resistant as NiB-X but suitable for some wear applications. Very happy but time will tell if it holds up, Just had one done last spring by Hayes Custom Guns 3gun (some USPSA) pistol and has held up great carried in a Kydex holster and not showing wear marks (yet). 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 hardness was above 50 Rc but was only a few tenths deep. 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. Our team has a tremendous width and depth of firearms industry expertise, with inhouse, master gunsmithing and firearm production capabilitiesto provide full spectrum performance to the firearms industry. 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. The physical vapour deposition techniques are widely used to deposit a wide range of materials on a number of base . 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. When steel parts are placed into a preheated liquid salt, there is sufficient energy localized near the surface due to . Do NOT ship the lower of the firearm as we are not transferring the firearm. PlatedReflective, plated finishes such as hard chrome, nickel and gold have been around longer than anyone presently reading this magazine. Just because it's not a through hardening (the term you were looking for) doesn't make it any less of a heat treat. Hard (harder than carbide, 3X hard chrome) Inert and stable material. Canton OH 44708. You can also add Nitride treatment and Cerakote products at the same time! To perform the test, I took the spacers I had made for my new 6-jaw chuck backplate and compared the results. Many users prefer to have a plasma oxidation step combined at the last phase of processing to produce a smooth jetblack layer of oxides which is resistant to wear and corrosion. That makes for extremely uniform surface coatings on parts with tight tolerances, like a triggers sear-engagement surfaces. You can also add Nitride treatment and Cerakote products at the same time! NiB coated bolt carrier groups are in the middle range on price, more costly than black nitride or phosphate but far less than Titanium Nitride. At a former job, we had lots of shafts nitrided. Black Nitride is supposed to harden the metal somewhat, and improve lubricity of moving parts. If you have an account, sign in now to post with your account.
