Cost effective plasma nitriding by using APPN – ADVANCED Pulsed Plasma Nitriding

APPN is an inexpensive and efficient way to enhance the fatigue strenght, Hertzian pressure and the hot hardness of tools. The process represents a most economically efficient processing of tools for molding, die casting, forging, extrusion of aluminum and various precision components. This type of surface thermochemical processing may be precisely controlled, which is necessary for subsequent combination of PVD or PeCVD with coating.
