Study on Plasma Nitriding Technology Imposed to Several Machine Parts Made of 40CrMo Steel

摘要

Plasma nitriding has been considered as the modern technology, enabling to form the nitriding layer on the surface which owns the high wear resistance, corrosion protection and enhances the fatigue resistance of the machine parts. This article presents the researches on plasma nitriding and the effects of several technology parameters on the quality of nitriding layer. This research results have been applied on a number of specific 40CrMo steel machine parts, such as hydraulic pumping gears, GN91 tractor transmission gears...
