THE POWER OF PULSED PLASMA ION NITRIDING

摘要

The use of the process of ion nitriding has opened the way to a more precisely controlled surface metallurgy on nitrided gears. The present use of the hot wall pulsed plasma ni-triding method now allows metallurgists the ability to prevent arc discharge and over heating experienced with the traditional methods of continuous dc plasma generation. The ability to manipulate the plasma glow by partial pressure adjustment to follow the tooth profile reduces the risk of non-uniform case formation in the tooth root. Pulsed plasma ion nitriding is a proven technology that offers clean processing with no toxic effluent on precise process control, controllable surface metallurgy, and a broad temperature operating band to reduce the risk of distortion and surface growth.
