I believe I have damaged the black nitride finish on my new Baretta Nano. Nitriding is like a low temperature (930 - 1020F) form of carburizing. Black Nitride treatment reduces hole damage caused by galling. Great service. Spray-on coatings are best-suited for rifle exteriors where the inevitable variations in thickness will not change tolerances nor impede function. It calls for no machining, or polishing or any other post-nitriding operations. Lost your password? The high temperature corresponds to carburizing temperatures. Bluing and Black Oxides are essentially the same thing. $50.00. The temperature used is typical of all nitrocarburizing processes: 550 to 570C. WMD Guns offers the following high-performance coating and surface treatment options: Our proprietary NiB-X coating process delivers the highest hardness rating in the nickel boron plating industry, exceeding Rockwell 70 C with post-treatment heating. Sothat could be a factor in deciding whether to choose this finish. Systematic investigation into the effect of nitrogen on the surface properties of steel began in the 1920s. I cannot keep a consistent oiled look. All of my concerns and questions were answered promptly and politely. 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. This cleaning procedure effectively removes the oxide layer from surfaces and may remove fine layers of solvents that could remain. Much research has taken place in recent decades to understand the thermodynamics and kinetics of the reactions involved. The coating is designed to release Teflon particles, the nickel wears and more Teflon releases. Looks like it came from the factory with a smoother finish. Black nickel is a derivative of nickel boron. Side Locks If you want to try Dicropan, its just $18.95 on Amazon. Plasma nitriding is often coupled with physical vapor deposition (PVD) process and labeled Duplex Treatment, with enhanced benefits. Paste as plain text instead, PO Box 80611. You can post now and register later. Thisarticle, "Any Color You Like," appeared originally as aRifles Column in the July 2017 issue of Shooting Illustrated. The steel turns blue quickly, after which you rinse it in cold water to remove and neutralize the chemicals. The reception in America was less impressive.

This process was invented by Bernhardt Berghaus of Germany who later settled in Zurich to escape Nazi persecution. Nitride Names like Melonite, Ni-Corr, Black nitride or salt bath nitride are all. tures placed the surface at risk to form what is known today as "nitride networks" (a saturated solution of nitrogen in the immediate surface of the formed case). This made it not desirableandalong with a higher cost, caused the switch to a phosphated coated bolt carrier group. In "Foundations of Mechanical Accuracy" the Moore boys use Nitralloy, which is an extremely expensive tool steel. Who will finish strong in a corrosion test (ASTM B117) featuring two barrels? All Rights Reserved. Your email address will not be published. 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. This way you gain the full benefit of Nitride treatment with the unlimited color and pattern options that Cerakote coating affords! Minimal amounts of material should be removed post nitriding to preserve the surface hardness.

One barrel coated in Cerakote Ceramic Coatings by T. Maybe it would accept more oil if you heated it GENTLY? But it uses sodium cyanide salt to case harden the part without the normal distortion of heat treating. Our NiB-X coatings are certified to ASTMB607 and/or AMS2433C. But, those firearms were too shiny for my liking (and out of my price range anyway). Communism only made one thing that works, and capitalism can make it even better. Chrome plating seems to do its best work inside of components subjected to high frictionbut not hard impactsand when done well, is still a great solution to limit erosion and wear. The black nitride treatmentis very durable and highly resistant to wear and it will not flake because it is not a coating. 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. BrianEnos.com Besides "don't clean your gun with brake cleaner", does anyone have any ideas? Specialized treatment outlasts conventional leader pins and bushings. [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 customer service was outstanding. The Midnight G10 camouflage handle is triple-riveted and built to withstand even the most vigorous slicing, dicing, and cutting.

There's a vast number of finishes available for AR-15 bolt carrier groups (BCGs . The coating on my slide turned out great. Our Big List of over 200 CNC Tips and Techniques. Titanium nitride coating applications are capable of dealing with wear caused by problems involving abrasions and adhesives. NiB-coated components are relatively easy to clean up but may become discolored when subjected to high heat. This technology is applicable to metals that can withstand the processing temperatures such as barrels, gas blocks, magazines, steel receivers, etc. 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. The standard-issue guns I later carried in the Army were all Parkerized. DCA Sig Sauer P365 Select Match Barrel. I simply cleaned them in some mineral spirits and then applied the compounds with a folded paper towel. Grip Color. This process permits the close control of the nitrided microstructure, allowing nitriding with or without compound layer formation. We offer Low, Medium, and High Phosphorous plating processes, as well as Electroless Nickel with Teflon, EN with Boron Nitride, and black EN plating. The coating has a Rc 70 and a coefficient of friction of .06. Core Pin hardness 50-55 HRC, comes complete with finished detail. 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. Back when I was knocking around the woods of my youth, I carried wood-stocked rifles with steel that was either blued or color-case hardenedand usually with a bit of surface rust around the margins. BlackNitride! One of the most expensive coatings to have on a bolt carrier group is titanium nitride or TiN. Thanks for the responses. Nickel-BoronNickel-boron (NiB) is an electroless gun coating, instead applied chemically. In a word: Rust. My conclusion was that the Dicropan looked darker, almost black, and seemed to go on more evenly. Proven to reduce the incidence of repair for stuck ejector pins. Another downside of the nickel boron coated bolt carrier groups is the finish will dull after time and take on a darker carbon color, even if the carrier is clean. The finished product was amazing as well!! We only custom mill slides. It is far cheaper than similar corrosion protection systems, such as paint and electroplating. When searching for a bolt carrier group to purchase, you will run across NiB or nickel boron. 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. Nitriding is not a finish in the industrial sense of the word and the loss of the dark color is not evidence of "wear". 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. Okay, so why bother coating steel with Cold Bluing or Black Oxide? 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! Cold bluing uses acids to put an oxidized finish on steel at room temperatures, or close to it. Today we have much better gun coating options for our ferrous-metal rifle parts. Internal components in those days were usually stainless, Parkerized, blued or sometimes left in the white..

This service includes the installation of a new Glock OEM channel liner. In case you were wondering, this is part of what I do for a living. JavaScript is disabled. When applying, the material is first coated with nickel boron, then it is treated in a salt nitride bath. More than that, Tungston, Aluminum are also used with mixing other metals. In the meantime, we offer a full array of NiB-X coated parts and firearms. On the other hand, the Oxpho-Blue showed more blues and was a prettier finish despite it being less even. For customers, this means unsurpassed wear protection. I believe I have damaged the black nitride finish on my new Baretta Nano. Come join the discussion about optics, hunting, gunsmithing, styles, reviews, accessories, classifieds, and more! Calico TiN is normally applied to steels, hardened steels, and stainless steel materials where high wear resistance and lubricity is needed. Uniform coating with no buildup on edges. The cost is pretty reasonable. Clear editor. My brother-in-law always has the latest cleaning products, so I rely on him to give me advice. You can blacken a number of materials including ferrous materials, stainless steel, copper, copper alloys, zinc, powdered metals, and silver solder. The nitrogen then diffuses onto the surface of the material creating a nitride layer. Hot Black Oxide involves hot baths of sodium hydroxide (the nasty stuff in drain cleaner), nitrates, and nitrites. The guys were nice enough to do my Taurus slide even though they dont work on them. Black Nitride adds roughly 3 weeks to your slide order. Join 100,000+ CNC'ers! Proven to reduce the incidence of repair for stuck ejector pins. NiB-coated components are relatively easy to clean up but may become discolored when subjected to high heat. 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. But it uses sodium cyanide salt to case harden the part without the normal distortion of heat treating. This page was generated at 11:14 PM. My personal favorite is the black nitride coated bolt carrier groups. 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. Ok, that's fair. Request a Range Partner Program sheet by contacting wynn@wmdguns.com. Sources for true match-quality, chrome-lined barrels can be counted on one hand, with fingers left over.
