On the other hand, the Oxpho-Blue showed more blues and was a prettier finish despite it being less even. Its high resistance to wear and corrosion also make it useful as an external surface protectant. A cadre of firearms performance experts formed WMD Guns to leverage these new firearm coating technologies and offer a full spectrum of premium products, coatings and services to the firearms industry. The Fora platform includes forum software by XenForo. Black Nitride (BN) is diffused .003-.005 into the component, and is not an additive process that can wear off and end up in your parts, like DLC and other surface coatings. You do as you wish, I really don't care. Only one process possible with a particular salt type - since the nitrogen potential is set by the salt, only one type of process is possible, This page was last edited on 18 January 2023, at 12:54. Pretty cool, eh? Definitely would recommend this service. Sources for true match-quality, chrome-lined barrels can be counted on one hand, with fingers left over. 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. The reception in America was less impressive. There are also cold plasmas, usually generated inside vacuum chambers, at low pressure regimes. Spray-on coatings are best-suited for rifle exteriors where the inevitable variations in thickness will not change tolerances nor impede function. A plasma nitrided part is usually ready for use. $0.00. This cleaning procedure effectively removes the oxide layer from surfaces and may remove fine layers of solvents that could remain. Examples of easily nitridable steels include the SAE 4100, 4300, 5100, 6100, 8600, 8700, 9300 and 9800 series, UK aircraft quality steel grades BS 4S 106, BS 3S 132, 905M39 (EN41B), stainless steels, some tool steels (H13 and P20 for example) and certain cast irons. http://www.matter.org.uk/steelmatter/manufacturing/surface_hardness/7_2_4.html, If this is your first visit, be sure to Rubbed in well.

"Gun control: The theory that a woman found dead in an alley, raped and strangled with her panty hose, is somehow morally superior to a woman explaining to police how her attacker got that fatal bullet wound." Nitromet Salt Bath Nitrocarburizing (i.e., Melonite). It calls for no machining, or polishing or any other post-nitriding operations. 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. Who will finish strong in a corrosion test (ASTM B117) featuring two barrels? The chemicals associated with these treatments convert a surface layer of the steel to magnetite. Limited wear and high temperature applications. A reference to this was in a previous thread ,what is it and how is it done? All Rights Reserved. It is a deposited copper selenium compound. The oldest and most widely used specification for hot black oxide is MIL-DTL-13924, which covers four classes of processes for different substrates. Can anyone give some feedback on Frog Lube? Nitriding is not a finish in the industrial sense of the word and the loss of the dark color is not evidence of "wear". When steel parts are placed into a preheated liquid salt, there is sufficient energy localized near the surface due to . 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. Sent in my p365 to have an optic cut and installed on it. Nitriding is like a low temperature (930 - 1020F) form of carburizing. Hot Black Oxide converts the surface into Magnetite. When components do not bond correctly (adhesive issues) wear can result as well. So, you have ignored the question. All times are GMT-5. 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. MPA DS9 Limited Optic Comp (LOC) $ 3,899.00. We provide options as there are many aftermarket slides with various coatings. For shops that want to do Cold Bluing in volume, the little kits for DIY Gunsmiths are prohibitively expensive. These processes are most commonly used on low-alloy steels. Plasma nitriding, also known as ion nitriding, plasma ion nitridingor glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. 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. The salts used are highly toxic - Disposal of salts are controlled by stringent environmental laws in western countries and has increased the costs involved in using salt baths.

First of all, let's get one thing straight; nitriding is NOT a coating. Since the process requires no electrical current, controllable coating deposition rates produce consistent tolerances within 1 to 2 microns. Be the first to offer your customers NiB-X coated firearms that are easier to clean and require little to no lubrication. The Ionbond Black DLC will not chip, crack or peel, providing you with years of protection against wear while maintaining its integrity. Most chromed bores are very durable, but they typically come up short in the accuracy department due to variations in thickness throughout the bore. Largest standard lock in the industry, sized for deflection resistance. Nickel-boron (NiB) is an electroless gun coating, instead applied chemically. (just the slide). Grip Color. Our engineered Electroless nickel plating processes can be tailored to provide various levels of hardness, wear, abrasion and corrosion resistance, and lubricity. There are vendors who know very well what they're doing with firearms and componentsand donitriding for both OEMs and aftermarket. Material: Stainless Steel 17-4. We were cleaning up our guns and he suggested non- chlorinated brake cleaner. Check out whats available from firms like Birchwood to see the more professional solutions. A barrel that is nitridedis going to be more accurate that a chrome lined barrel because chrome plating takes away some of the sharpness of the rifling. 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 customer service was outstanding. Because nitriding involves heating poisonous salts to high temperatures, I don't think it's practical in a home shop. A critical marksmanship skill that is easy to overlook. Leader Pins and Bushings Specialized treatment outlasts conventional leader pins and bushings. Extremely strong adhesionmolecular bond to substrate metal. Kasenit is not nitriding -- it's not even close. By Ionbond Diamond-like Carbon is a metal finish applied through a Physical Vapor Deposition (PVD) process. Black Nitride. Black Nitride adds roughly 3 weeks to your slide order. Required fields are marked *. One barrel coated in Cerakote Ceramic Coatings by T. Minimal amounts of material should be removed post nitriding to preserve the surface hardness. Still not as wear resistant as NiB-X but suitable for some wear applications. If you have an account, sign in now to post with your account. TiN is a thinly-applied surface coating has a shiny gold-like appearance and is often used for show builds due to aesthetics. 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. Spray-ons have the added benefit of being equally well-suited for aluminum, polymer and wooden rifle components, too. 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. Hot Black Oxide converts the surface into Magnetite. The DS9 LOC is a 9mm Minor Pistol intended for use in USPSA Limited Optics Division. As for cosmetics, the wear properties of the surface may be a concern for some people, even if the underlying metal isn't affected. In gas nitriding the donor is a nitrogen-rich gas, usually ammonia (NH3), which is why it is sometimes known as ammonia nitriding. This service includes the installation of a new Glock OEM channel liner. Making stainless black is a side effect and even if the color wears away the metallurgical properties are unchanged. 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. The onyx-black, Titanium Nitride coating reduces friction and preserves the steel against corrosion. Clear editor. Join 100,000+ CNC'ers! 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 . Consistent color across the slide with no imperfections anywhere. WMD was a pioneer in of nickel boron technology in the firearms industry, and not only is our coating formula unique; our application process is, as well. The Cold processes produce a similar color, but the coating tends to rub off more easily and offer less abrasion resistance. Here are some alternatives to the buffed blue and phosphated-gray rust magnets of days gone by. This way you gain the full benefit of Nitride treatment with the unlimited color and pattern options that Cerakote coating affords! Items sent in only for black Nitride have a 3-6 week turn around time. Please remove the irons and all internals. The key to our engineered nickel boron plating processes is versatility. Looks better than a factory cut. If you fail to do this we will refund the order and returnthe slides. The only other option I was aware of at the time was bright stainless steel. Turn around time was quick as well, especially during the holidays. Nitromet Salt Bath Nitrocarburizing (Melonite, Tennifer, Black Nitride) This process is the new industry leader in bore coatings for firearm barrelsachieving a 30% greater lifespan in the bore than chrome! SKU: PINS-TDPIV-BLK. NiB-coated components are relatively easy to clean up but may become discolored when subjected to high heat. PO Box 80611. NiB-X firearms must be properly maintained and available to consumers throughout the 3 month period. 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]. In the plasma nitriding processes, nitrogen gas (N2) is usually the nitrogen carrying gas. First class company and customer service. 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. It is a tough corrosion proof coating, with excellent friction properties. Nitriding is like a low temperature (930 - 1020F) form of carburizing. 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. The nitrogen then diffuses onto the surface of the material creating a nitride layer. 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). Setting A New Standard In Metal Processing Share Watch on The material was 1018 and 1214. Posted by William Roberts on Oct 28th 2022. The nitriding process actually becomes part of the material being treated . This isn't something I'm going to debate with amateurs. These finishes are susceptible to harsh chemical strippers like acetone or ammonia-based solvents, so stick to safer cleaners like mineral spirits or conventional powder solvents when cleaning painted rifles. Black Nitride Black Nitride and dry to touch oil (BN) Cadmium Platings Cadmium Plus Clear Chromate (CI) Cadmium Plus Metric Blue Chromate (CB) Cadmium Plus Olive Drab Chromate (CO) Cadmium Plus Yellow Chromate (C) Cadmium Without Finish Coat (D) Dry Film Lubricants Carbowax (CW) Electro-Film (EF) Molybdenum Disulfide Dry Film Lubricant (MD) Black Nitride treatment reduces hole damage caused by galling. I then oiled the parts with Break Free, which is also an excellent anti-corrosive. They differ somewhat in composition and may be air- or heat-cured. High hardness of 66-70 HRC that is suited for harsh conditions. I swear they began turning rust-orange as soon as I looked away unless they were slathered with CLP. I cannot keep a consistent oiled look. They used a liquid bath at about 1100F. Do NOT ship the lower of the firearm as we are not transferring the firearm. Black Nitride Slide Coating. Side Locks An innovative way to carry your backup gun. BlackNitride! Solution must be vigorously agitated during plating to ensure the BN particles remain suspended in the solution. 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). 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. Posted by Boban Jancevski on Feb 6th 2023. This component features a black nitride coating. Display as a link instead, However, if the nature of your rifle work requires something more practical, aim for components coated with a modern, durable and cost-effective surface treatment. Plasma nitriding is often coupled with physical vapor deposition (PVD) process and labeled Duplex Treatment, with enhanced benefits. For a better experience, please enable JavaScript in your browser before proceeding. No one would ever question that austenitizing and quenching high carbon alloy steels is a heat treatment, even though all it does is produce a hard outer case and doesn't appreciable alter the core properties; same as nitriding. We've been coating medical implants with titanium nitride for years in our ISO 13485 facility. Calico TiN is normally applied to steels, hardened steels, and stainless steel materials where high wear resistance and lubricity is needed.
