The 12M and 12N engines were the first to use the gas nitriding surface hardening process on the cylinder walls, which reduced both wear and oil consumption.
22.
A Swiss steel pan manufacturer ( PANArt ) researched the field of fine-grain sheet steel and developed a deep-drawn raw form which was additionally hardened by nitriding.
23.
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.
24.
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.
25.
Ipsen's industrial furnaces-vacuum furnaces, atmosphere furnaces and pusher-type furnaces-are used for the following heat treatment processes : annealing, vacuum brazing, temperature brazing, plasma nitriding
26.
During manufacture, propeller pistons, which control the pitch of the propellers, are coated through a process called " nitriding ", which hardens them and makes them more resistant to surface wear.
27.
This also helps the thermal stability of the plasma plant, since the heat added by the plasma is already present during the warm up and hence once the process temperature is reached the actual nitriding begins with minor heating changes.
28.
The engine was built in Spain as the "'Hispano-Suiza 5Q "'or "'Hispano-Wright 5Q "'without modification apart from the use of Hispano's patented nitriding finishing process.
29.
Case-hardened steel is formed by diffusing carbon ( carburization ), nitrogen ( nitriding ) and / or boron ( boriding ) into the outer layer of the steel at high temperature, and then heat treating the surface layer to the desired hardness.
30.
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.
