Process: Gas Carburising, Neutral Hardening and Nitrocarburising with two pots.

Ferritic nitrocarburizing or, less commonly known as Ferritic nitrocarburising, in British English, is a range of case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures.

Gas nitriding see Nitriding Gas nitrocarburising See Nitrocarburising Galvanising A hot dip process for deposition of zinc for galvanic corrosion protection of steel.

It is also used for the heat treatment of metals (e.g., Ferritic nitrocarburizing).

The trade name and patented processes may vary slightly from the general description, but they are all a form of ferritic nitrocarburizing.

Glock introduced ferritic nitrocarburizing into the firearms industry as an anticorrosion surface treatment for metal gun parts.

There are four main classes of ferritic nitrocarburizing: gaseous, salt bath, ion or plasma, and fluidized-bed.

Because of the cleaning issues the Joseph Lucas Limited company began experimenting with gaseous forms of ferritic nitrocarburizing in the late 1950s.

Plasma-assisted ferritic nitrocarburizing is also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding.

The gas used for plasma nitriding is usually pure nitrogen, since no spontaneous decomposition is needed (as is the case of gaseous ferritic nitrocarburizing with ammonia).

Pistol manufacturer Caracal International L.L.C. uses ferritic nitrocarburizing for finishing parts such as barrels and slides with the plasma-based Plasox process.

Some of the different diffusion hardening operations include: Carburizing, Nitriding, Carbonitriding, Nitrocarburizing, Boriding, Titanium-carbon diffusion, and Toyota diffusion.

Ferritic nitrocarburizing or, less commonly known as Ferritic nitrocarburising, in British English, is a range of case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures.

Ferritic nitrocarburizing: A case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures to improve scuffing resistance, fatigue properties and corrosion resistance of metal surfaces.

Besides Glock several other pistol manufacturers, including Smith & Wesson and Springfield Armory, Inc., also use ferritic nitrocarburizing for finishing parts like barrels and slides but they call it Melonite finish.

Salt bath ferritic nitrocarburizing is also known as liquid ferritic nitrocarburizing or liquid nitrocarburizing and is also known by the trademarked names Tufftride and Tenifer.

Gaseous ferritic nitrocarburizing is also known as controlled nitrocarburizing, soft nitriding, and vacuum nitrocarburizing or by the tradenames Nitrotec, Nitemper, Deganit, Triniding, Corr-I-Dur, Nitroc, and Nitrowear, Nitroneg.
