Nitriding has the purpose to increase the surface hardness in order to improve the wear-resistance. This can be achieved by diffusing nitrogen or nitrogen in combination with carbon into the work piece.

Possible Nitriding Processes

Gas Nitriding

Under amoniacal gas, at temperatures of 500 - 530°C, depth of nitration: 0.1-0.9mm.

Plasma Nitriding

Under vacuum through plasma, at temperatures of 350 - 580°C, depth of nitration: 0.1-0.9mm


Under amoniacal gas with the addition of carbon, at temperatures of 540 - 630°C, normally a nitrocarburized layer of 10 - 25 µm can be achieved.
