Following this the ion nitriding process was invented in the early 1980s.
2.
For the nitriding process H 2 gas is also added to keep the surface clear of oxides.
3.
In the plasma nitriding processes, nitrogen gas ( N 2 ) is usually the nitrogen carrying gas.
4.
The slide and other metal parts of the pistol are Tenifer treated ( a nitriding process also used on Glock pistols ).
5.
The surface of the metal has undergone a Melonite treatment, a salt bath nitriding process which leaves a hard, corrosion-resistant surface.
6.
Indeed, Argon and H 2 can be used before the nitriding process during the heating of the parts to clean the surfaces to be nitrided.
7.
After heat treatment the metal parts are finished with a proprietary nitriding process called concealed, as the highly chloride-resistant finish allows the pistol to better endure the effects of perspiration.
8.
Most of the steel components in a Glock pistol are treated with a nitriding process called " Tenifer ", which increases the surface hardness and makes the pistol resistant to corrosion and wear.
9.
New guns are typically available in blued finish options offered as the least-expensive finish, and this finish is also the least effective at providing rust resistance, relative to other finishes such as Parkerizing or hard chrome plating or nitriding processes like Tenifer.
