How good is Melonite coating?
How good is Melonite coating?
Unlike some other finishes and treatments, Melonite® has a predictable and consistent outcome that significantly strengthens the surfaces of carbon steel, stainless steel, alloy steel, and austenitic steel products. It can also be highly effective when used for cast iron and sintered iron, as well.
Is Melonite the same as nitride?
Nitride is a treatment to the barrels steel that hardens the steel and significantly increases corrosion and wear resistance. Melonite is a specific version of Nitride but for the most part Melonite and Nitride are the same.
What is Melonite QPQ finish?
From Wikipedia, the free encyclopedia. Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite.
How hard is QPQ?
The Melonite® and QPQ process increases fatigue strength about 100% on notched components made from unalloyed steel parts and about 30-80% on parts made of alloyed steels. The hardness is maintained up to about 930°F and extends the surface life of steel tools and components exposed to heat.
What is Melonite used for?
Melonite® is a thermochemical treatment for improving the surface properties of steel parts. It exhibits predictable and repeatable results in the treating of low and medium carbon steels, alloy steels, stainless and austenitic steels, tool and die steels, cast and sintered iron.
What color is Melonite?
Melonite is a telluride of nickel; it is a metallic mineral. Its chemical formula is NiTe2. It is opaque and white to reddish-white in color, oxidizing in air to a brown tarnish….

What is the best firearm coating?
Black Oxide (Bluing) As one of the least expensive corrosion-resistant finishes on the market, black oxide is often the preferred finish used on gun barrels and small components. Gun oil is important to this type of finish to avoid rusting.
What is a Melonite coating?
Melonite is basically salt bath ferritic nitrocarburizing, also known as liquid nitrocarburizing. Melonite is also called Tenifer by Glock. It is the finish we use on all our black slides and its durability is unparalleled by any black finish we have used.
Is Qpq a coating?
Quench Polish Quench or QPQ coating is a sophisticated heat treatment for ferrous metals such as steels and iron. The main idea to use the QPQ process is to achieve very high corrosion resistance and lubricity.
What is black Melonite?
Which is better DuraCoat or Cerakote?
DuraCoat – Weighing Your Options For the Best Firearm Finish. Cured Cerakote absolutely beats cured DuraCoat in every measurable respect with regard to finish quality, abrasion resistance, and overall toughness.
What is the most durable firearm finish?
Black Oxide (Bluing) As one of the least expensive corrosion-resistant finishes on the market, black oxide is often the preferred finish used on gun barrels and small components. Gun oil is important to this type of finish to avoid rusting. Methods used are either a hot or cold process.
Melonite ® is a thermochemical treatment for improving the surface properties of steel parts. It exhibits predictable and repeatable results in the treating of low and medium carbon steels, alloy steels, stainless and austenitic steels, tool and die steels, cast and sintered iron.
What are the stages of the Melonite treatment system?
The system has many stages, from the pre-treatment-cleaning, to pre-heat furnace, to the Melonite salts, oxidizing salts, and water-cooled and rinsed. Both Melonite and Melonite QPQ are used to improve the surface properties of plain carbon, low alloy, and stainless steels.
What is the difference between melonite and chrome lining?
Whereas Melonite and chrome-lining processes are used for the same purpose, coating and/or finishing barrel treatment, they achieve the goal differently. Unlike nitriding, which changes the surface properties, chrome lining adds a coating to the interior barrel surface that can be as thick as one-and-a-half thousandths, 0.0015″.
What are the benefits of Melonite barrels?
Here’s a quick summary of the benefits of Melonite barrels: It is a single process in comparison to chrome plating that requires phosphating of the exterior barrel surface Compared to the bare chrome-moly steel barrels, the Chome-lined barrels are more heat, chemical, and erosion-resistant.
