Gas Nitriding - Total Materia

Gas nitriding is a case-hardening process whereby nitrogen is introduced into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia. The nitriding temperature for all steels is between 495 and 565°C (925 and 1050°F). Principal reasons for nitriding are:Fatigue strength improvement of a hard chromium plated pdf effect of plasma nitriding pretreatment on theJan 13, 2006 · An application of the PN pretreatment before the plating process was effective in improving the fatigue performance of HCcoated steel. An improvement of 71% in the fatigue strength of pretreated specimens was recorded as compared with the specimens, which were HC plated only.
