DLC. We only custom mill slides. We provide options as there are many aftermarket slides with various coatings. Thus the process is user-friendly, saves energy since it works fastest, and causes little or no distortion. 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. This process has existed for nearly a century, though only in the last few decades has there been a concentrated effort to investigate the thermodynamics and kinetics involved. Plasma nitriding is often coupled with physical vapor deposition (PVD) process and labeled Duplex Treatment, with enhanced benefits. 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. SKU: PINS-TDPIV-BLK. A critical marksmanship skill that is easy to overlook. Upload or insert images from URL. Some internet experts are of the opinion that nitriding compromises the material and makes it unsafe. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); My conclusion was that the Dicropan looked darker, almost black, and seemed to go on more evenly. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound. Calico TiN is normally applied to steels, hardened steels, and stainless steel materials where high wear resistance and lubricity is needed. You do as you wish, I really don't care. We trust these pins to perform in the harshest conditions.. Spray-on coatings are best-suited for rifle exteriors where the inevitable variations in thickness will not change tolerances nor impede function. Through the H&M Blacknitride+ process, or Ferritic Nitrocarburizing, we can improve the operational capabilities of your components, solving wear, lubricity and corrosion resistance problems. I have been using nitrided barrels, bolts and trigger groups for years and have yet to wear one out. The guys were nice enough to do my Taurus slide even though they dont work on them. Other gasses like hydrogen or argon are also used. The standard-issue guns I later carried in the Army were all Parkerized. [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 processes are named after the medium used to donate. These processes are most commonly used on low-alloy steels. Uniform coating with no buildup on edges. Each has its pros and cons, but all provide better protection from the elements than the coats of old. I've had several of my guns Pvd coated by Richter precision. Come join the discussion about optics, hunting, gunsmithing, styles, reviews, accessories, classifieds, and more! As for cosmetics, the wear properties of the surface may be a concern for some people, even if the underlying metal isn't affected. 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.

Proven to reduce the incidence of repair for stuck ejector pins. Kasenit is not nitriding -- it's not even close. The Cold processes produce a similar color, but the coating tends to rub off more easily and offer less abrasion resistance. In case you were wondering, this is part of what I do for a living. My conclusion was that the Dicropan looked darker, almost black, and seemed to go on more evenly. 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. Son, you don't know what you don't know about the subject. When components do not bond correctly (adhesive issues) wear can result as well. Price was very reasonable. Setting A New Standard In Metal Processing 22,072 views Aug 31, 2018 253 Dislike Share GUNS and American Handgunner Magazines 63.5K subscribers H&M BlackNitride brings their aerospace. The exact materials yo can blacken will be based on the recommendations of the makers of the particular chemicals or kit you use. Enjoy the comfort of its rugged grip, resistant to both extreme hot and cold temperatures for long-term durability. [2] When ammonia comes into contact with the heated work piece it dissociates into nitrogen and hydrogen. I believe I have damaged the black nitride finish on my new Baretta Nano. Do NOT ship the lower of the firearm as we are not transferring the firearm. Much research has taken place in recent decades to understand the thermodynamics and kinetics of the reactions involved. TiN is the staple of Physical Vapor . I need cost effective bolt carriers thatare strong, protected and dont wear fast. NiB-coated components are relatively easy to clean up but may become discolored when subjected to high heat. In a word: Rust. Systematic investigation into the effect of nitrogen on the surface properties of steel began in the 1920s. Excellent finish. Proven to reduce the incidence of repair for stuck ejector pins. "Nitride" is typically a generic term referring to "nitriding, nitrocarburizing, or gas nitriding" of steel- a metallurgic process that increases surface hardness and decreases corrosion. By This process was invented by Bernhardt Berghaus of Germany who later settled in Zurich to escape Nazi persecution. After his death in late 1960s the process was acquired by Klockner group and popularized globally. Our Big List of over 200 CNC Tips and Techniques. 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). 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. 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. 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 durability and corrosion protection offered by black nitride treatment is unmatched by any other coating available. Outdoor Hub, LLC (d/b/a Carbon Media Group), 30800 Telegraph Rd, Suite 1921, Bingham Farms, MI 48025 USA. If holster wear/durability is a concern then we highly recommend going with our Black Nitride as Cerakote is a wearable item. 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. Request a Range Partner Program sheet by contacting wynn@wmdguns.com. Were experts in all the tolerances and variables that are crucial for optimizing firearms performance. By the way, I asked in the Tailstock thread (where John first suggested Nitriding the tailstock ram) whether you need special steel to nitride. Material: Stainless Steel 17-4. Unlike PVD processes such as diamond-like coatings (DLC), black nitride penetrates the steels substrate and wont chip, flake, or peel.. Pretty cool, eh? NiB reduces friction and speeds the cooling of high-heat components due to the increased surface area created by the coatings texture. Be the first to offer your customers NiB-X coated firearms that are easier to clean and require little to no lubrication. For fun I compared the finish from two Brownells cold bluing products: Dicropan T-4 and Oxpho-Blue Creme Cold Bluing Test. With rigorous precision, we create and deliver the finished product on time and at a great value. The process was greeted with enthusiasm in Germany and several steel grades were developed with nitriding in mind: the so-called nitriding steels. Here are some alternatives to the buffed blue and phosphated-gray rust magnets of days gone by. Copyright 2023 National Rifle Association. Coating can be duplexed with sublayers or topcoats to enhance specific properties customers may desire. This treatmentis great for use on barrels to prevent corrosion and increase barrel life. They can and do serialized items, but will only accept from an FFL. In plasma nitriding, the reactivity of the nitriding media is not due to the temperature but to the gas ionized state. NiB reduces friction and speeds the cooling of high-heat components due to the increased surface area created by the coatings texture. Pasted as rich text. When applying, the material is first coated with nickel boron, then it is treated in a salt nitride bath. Ideas expressed may be mine, or from anyone else in the universe. 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. Investigation into gas nitriding began independently in both Germany and America. Who will finish strong in a corrosion test (ASTM B117) featuring two barrels? WMD Guns will coat pistols, rifles (ARs, bolt actions, semi-automatics) and shotguns. Largest standard lock in the industry, sized for deflection resistance. NitrideNames like Melonite, Ni-Corr, Black nitride or salt bath nitride are all variations of a surface treatment formally known as Liquid Salt Bath Ferritic Nitrocarburizing Non-Cyanide Bath (FNC) or simply nitriding. A forum community dedicated to all firearm owners and enthusiasts. The nitrogen then diffuses onto the surface of the material creating a nitride layer. Items sent in only for black Nitride have a 3-6 week turn around time. So, you have ignored the question. All times are GMT-5. 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. Hot Black Oxide converts the surface into Magnetite. 172 votes, 80 comments. Titanium nitride coating applications are capable of dealing with wear caused by problems involving abrasions and adhesives. But it uses sodium cyanide salt to case harden the part without the normal distortion of heat treating. The nitriding was done by an outside vendor. Internal components in those days were usually stainless, Parkerized, blued or sometimes left in the white.. This process isn't commonly used due to the expense in treating the bolt carrier twice. On this Wikipedia the language links are at the top of the page across from the article title. To subscribe to the magazine,visit theNRA membership page hereand select Shooting Illustrated as your member magazine. 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 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. Free delivery for many products! The coating has a Rc 70 and a coefficient of friction of .06. In 2015, nitriding was used to generate a unique duplex microstructure in an iron-manganese alloy (martensite-austenite, austenite-ferrite), known to be associated with strongly enhanced mechanical properties.[7]. 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. Attempts to chrome-line rifle bores date back to the first half of the 20th century. In this technique intense electric fields are used to generate ionized molecules of the gas around the surface to be nitrided. For questions and more information on our Black Nitride offering: Progressive's Black Nitride Core Pins outlast all other 5 to 1. We were cleaning up our guns and he suggested non- chlorinated brake cleaner. More durable thancerakoteor bluing. Nitriding is not a finish in the industrial sense of the word and the loss of the dark color is not evidence of "wear". Cerakote vs. Black Nitride. It calls for no machining, or polishing or any other post-nitriding operations. MPA DS9 Limited Optic Comp (LOC) $ 3,899.00. Even though I own a couple nickel boron bolt carrier groups, I dont need a shiny parts to look cool. It is far cheaper than similar corrosion protection systems, such as paint and electroplating. Leader Pins and Bushings Specialized treatment outlasts conventional leader pins and bushings. They used a liquid bath at about 1100F. JavaScript is disabled. The treatment results in a deep jet-black color compared to our Black DLC (PVD) coating which is a dark "smokey black" color. Nickel-boron (NiB) is an electroless gun coating, instead applied chemically. currahee1911 Parts coated with the NiB-X nickel boron process are suited to a wide range of applications. PlatedReflective, plated finishes such as hard chrome, nickel and gold have been around longer than anyone presently reading this magazine. Hot Black Oxide involves hot baths of sodium hydroxide (the nasty stuff in drain cleaner), nitrates, and nitrites. The WMD Range Partners Program was created to help ranges to increase rentals and sales, provide sales assistance at the retail level and raise consumer awareness and knowledge of WMD Guns/NiB-X products. Minimal amounts of material should be removed post nitriding to preserve the surface hardness. You can post now and register later. Unbelievable Finish!!! Its a surface treatment which isnot the same as a full heat treat. Core Pin hardness 50-55 HRC, comes complete with finished detail. 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. I would like them to do rifle barrels too. 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! Availability: Within 1 day. All Rights Reserved. Black Nitride is becoming more common and slowly replacing the parkerizing of steel parts. It is a tough corrosion proof coating, with excellent friction properties. The advantages of salt nitriding is that it achieves higher diffusion in the same period of time compared to any other method. The DS9 LOC is a 9mm Minor Pistol intended for use in USPSA Limited Optics Division. Please remove the irons and all internals. You people realize that nitriding is a heat treatment and that its purpose is to change the metallurgy of the steel? Nitriding vastly increases the hardness of the metal that is treated without changing the material dimensionally like the build up of a hard coat. Black nickel is a derivative of nickel boron. Maybe the Kleenbore product is not getting it done. I've had several of my guns Pvd coated by Richter precision. As for cosmetics, the wear properties of the surface may be a concernfor some people,even if the underlying metal isn't affected. 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. NiB provides excellent corrosion resistance, but over time it will give way to the ravages of high heat and pressure on hard-use components. It has the same material properties throughout the structure of the coating so integrity and properties are maintained throughout the thickness. Because nitriding involves heating poisonous salts to high temperatures, I don't think it's practical in a home shop. While no longer popular on long gun exteriors, surface treatments like chrome-plating work well on and in certain internal components. 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. Most tactical-rifle shooters have experience with chrome-lined bores, which provide wear- and corrosion-resistance. 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. The most used drill bit materials are HSS, cobalt, and titanium. BlackNitride! Turn around time was quick as well, especially during the holidays. Chrome-plated parts are slicker than bare steel, allowing for easier cleanup of pistons and bolt components. Sources for true match-quality, chrome-lined barrels can be counted on one hand, with fingers left over. 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 .
