Austrian firearms manufacturer Glock Ges.m.b.H uses the Tenifer process on the slides and barrels of its handguns. Home / Blog. Let’s take a look at both of them, and you can make the final winner in a battle of Duracoate vs Cerakote: Cerakote vs DuracoatRound 1: What Are They?! Also, from a cost standpoint, would it be worth the hassle. Melonite or Anodized? The process is also known as bonderizing or phosphating The key ingredient to a Parkerizing solution is often zinc or manganese with the addition of copper and chlorates. Nitromet Salt Bath Nitrocarburizing (Melonite, Tennifer, Black Nitride) This process is the new industry leader in bore coatings for firearm barrels—achieving a 30% greater lifespan in … When the conversion process is complete, the stream of bubbles will cease. Picture: JP Enterprises .750 Adjustable Gas Block in QPQ Black Finish. I've heard and read about guns with these finishes being more difficult to work on. First of all, there are many names for “Melonite.” It is often referred to as Black Nitride, Nitride and Tenifer. I found info for one guy on the site but it was dated quite a while back... so lets update the list for myself and others that may be interested. Alloy parts are also pretreated for improved adhesion and protection. The tennifer and melonite finish are the same thing. In these and other industries, Melonite® QPQ® processing has a number of applications, including: These are just a few of the ways that Melonite® QPQ® finishing is used in multiple industries for numerous purposes. Melonite is ferretic nitrocarburizing which is closer to case hardening then blueing but still uses a salt bath. Nickel Plating ... sent for refinishing will be fitted with a new plunger tube which is also included in pricing of the finish. I have done some reading on the melonite finish, but before I fudge it up, I would like to know if I have the correct info on cleaning and lube products. The first step of the process is a preheat to raise the components surface temperature to about 700 - 800°F in air. Precise cut RMR dovetail with location bosses; Use new Gen 5 Internals; Tighter tolerances for increased accuracy, reliability, and performance. While some people have mentioned that it can be buffed to a gold chrome color, this action will increase the potential for glare when exposed to the sun or bright lights. Other methods of ferric nitrocarburizing include gaseous process such as Nitrotec and ion (plasma) ones. The first step of the process is a preheat to raise the components surface temperature to about 700 - 800°F in air. Ever wondered what the difference was between Cerakote vs. PVD? Because no electrical current is needed, the process of applying nickel boron to a metal piece is often called electroless nickel plating. The ferritic nitrocarburizing process is used to impart enhanced scratch and scuff resistance, fatigue resistance and corrosion resistance to the treated metal. Black Nitride goes by a few names, Ferritic Nitrocarburizing, Melonite, SBN "salt bath nitriding", QCP and Tenifer, that are all names for the same thing, the only difference would be Tenifer, this process is used in Europe with a different cyanide formulation bath "EPA wont allow that in the US". PVD coatings deliver unrivaled toughness and great lubricity, but are so micro-thin they don’t interfere with operation. Thanks to Melonite® (also called Tenifer® or Tufftride®), you can get the finest case hardening process to ensure the best performance for your products for years to come. Learn more about our Melonite ® coating, media blasting and paint stripping services below or contact us to discuss your metal finishing project. The salt bath solution includes alkali cyanate as a key ingredient. Stephen G Dotson. Melonite QPQ Process The Melonite QPQ process is a multi step process that provides a very uniform consistent nitride layer on your components. The parts are then fully quenched and rinsed using a water bath. Cerakote is a ceramic-based coating which is available in various colors. Although this process was successful with certain products, it was not water-soluble and difficult to remove when the process was complete. I like what many museums use to preserve the finish on various things. All steel parts are parkerized for an additional layer of rust and corrosion protection. Contact us at IBC Coatings online at This email address is being protected from spambots. The relatively low processing temperatures of this process cause only minor shape distortion, along with decreased thermal shock to the metal from temperature changes. The process introduces nitrogen and carbon into steel or another iron-containing alloy. The melonite coating if VERY corrosion resistant on both stainless and non-stainless steel. Melonite QPQ Process The Melonite QPQ process is a multi step process that provides a very uniform consistent nitride layer on your components. The second process is hot bluing and uses alkali salt. Melonite is a telluride of nickel; it is a metallic mineral. IBC Coatings Technologies uses a thermochemical quench-polish-quench (QPQ® see registered trademarks disclaimer at the bottom of the page) nitriding process equivalent to Melonite® to harden, strengthen, and improve the corrosion resistance of metal components and equipment.

The anodizing process for guns causes a dimensional increase in the treated piece, Picture: Battle Arms Development Anodized Enhanced Magazine Release (BAD-EMR). SUAREZ SUPERMATCH SI-519 TRIJICON RMR SLIDE (FOR GEN 5 G19) - BLACK MELONITE. var addy54e123f8ebea0ce04f240d07fee10245 = 'info' + '@'; Depending on the ingredients, a phosphatized piece of metal will range in color from medium-gray to black.
