Open full text 2 citations

Abstract

In this study, low temperature plasma carburizing technology as one of the surface hardening techniques has been applied to improve the mechanical properties of 304 austenitic stainless steel. Several low temperature process parameters were studied to focus on the structure and properties of the carburized layer. The results shows that carburizing at 450°C, C3H8: H2 = 1: 40, carburizing time 10h could get a better white layer, a better wear resistance and a reasonable corrosion resistance, which proved to be the optimal hardening treatment.
