Effect of Process Temperature on the Microstructure and Properties of Low-Temperature Gas Multi-Component Thermochemical Treatment 45CrMoV Alloy Steel

Abstract

In the present investigation, 45CrMoV alloy steel was gas oxynitrocarburized at 530°C, 550°C and 570°C for 1h by applying a low-temperature gas multi-elements penetrating system. Microstructure, surface, composition, case depth, microhardness, wears and corrosion resistance were analyzed. The properties of samples treated at 570°C are optimum.
