How good is the black nitride finish?
A black nitride surface is very corrosion resistant, it doesn’t corrode underneath as chroming or rust through as parkerizing does and is very durable. It is NOT black paint or a surface coating.
What is black nitride coating?
BLACK NITRIDE AND DRY TO TOUCH OIL( BN ) Parts are heat treated to give them a thin, hard, durable case with a dark brown to black color. Compound layer meets requirements of Section 3.4 of SAE AMS2753. Dry to touch oil added to improve appearance and corrosion resistance.

Is Melonite better than nitride?
Nitride is a treatment to the barrels steel that hardens the steel and significantly increases corrosion and wear resistance. 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.
What is Melonite finish?
What is Melonite® Nitrocarburizing? 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.
Is black Nitride the same as Melonite?
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.
How thick is Melonite coating?
about 10-20 µm thick
Treatment durations of 1-2 hours usually yield compound layers about 10-20 µm thick (0.0004 – 0.0008″).
What is the difference between Tenifer nitride and Melonite finish?
So, a Tenifer nitride finish will be thinner than a Melonite finish. After the salt bath, the piece goes through various polishing processes. This second process includes vibratory finishing, lapping, and also center-less grinding. After this process, you will have a mottled gray surface.
Is Melonite the same as nitride?
Is Melonite The Same as Nitride? Generally, yes, because both names represent a salt bath process where the barrels are treated inside and out. Melonite, Tenifer, or Tufftride are all branding terms for various similar chemical processes performed at high temperatures to create a Nitride layer on the steel.
Is Melonite coating better than chrome plating?
Some manufacturers even claim that their Melonite coating is 85 percent more resistant to corrosion than chrome plating. One more notable advantage is that Melonite does not shrink nor enlarge the barrel at all, or reduces the rifling’s sharp edges.
Is black nitride finish better than phosphate on guns?
Both phosphate and nitride have good corrosion-resistance. However, nitride is slightly more resistant than phosphate. Phosphate needs to be lubricated with gun oil much more than nitride to keep rust specks forming on the outside and even the inside of your gun. Black Nitride Finish (Photo credit: tacticalshit.com)
