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.
What is 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.
What is Melonite Qpq?
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.
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….

Can you Melonite aluminum?
We can apply MAD Black to any type of metal including aluminum, steel, stainless steel, brass, copper, etc. NP3, NP3 plus, Melonite finishes and TiN can only be applied to ferrous metals.
Is Melonite and nitride the same?
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.
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.
Is Melonite better than Chrome?
The melonite coating provides a thinner surface than chrome-lining, so bore friction is reduced for better accuracy. In addition, melonite is harder than chrome-lining providing a longer wear life.
Is Melonite better than nitride?
This is usually done in a process called Quench polish quench (QPQ). Melonite is a specific version of Nitride but for the most part Melonite and Nitride are the same. But the biggest take away from the test is the Nitride barrel held its accuracy better.
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 can Melonite be used for in steel treatment?
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.
How is the Melonite process done in a furnace?
The MELONITE process also begins with the placement of parts in a re-circulating air preheat furnace, followed by immersion for 60-240 minutes in a molten nitrogen-rich MELONITE specific salt solution contained in an aerated furnace. After nitriding, parts are treated in an oxidizing bath, water-cooled and rinsed.
What’s the difference between melonite and hard chrome?
Melonite is not a coating, will not wear away, and provides a higher level of protection than hard chrome, nickel, and similar metal plating methods. The Melonite process is an environmentally-friendly alternative that creates a durable black finish and causes no distortion.
What kind of salt is used to make Melonite?
Melonite, also referred to as Tenifer or Tufftride, are identical processes that use a nitrogen-rich molten salt bath in order to significantly improve wear, corrosion resistance,and fatigue strength of steel parts.
