STUDY ON PLASMA NITRIDING TECHNOLOGY FOR SOME MACHINE COMPONENTS MADE OF 40CRMO STEEL.

Abstract

                  Plasma nitriding has been considered as a modern technology enabling to form a nitring layer on the machine components’surface which has the properties of high wear resistance, corrosion protection and enhance fatigue resistance of the machine components.

This article presents researches on plasma nitriding and the effects of several technology parameters on the quality of nitriding layer. This technology has been applied for such specific machine components made of 40CrMo steel as hydraulic pumping gears, GN91 tractor transmission gears...
