In this study, in order to explore a suitable method to obtain a better wear resistance and corrosion resistance of austenitic stainless steel, low temperature plasma carburizing technology has been studied. Research on the properties of austenitic stainless steel under different carburizing atmosphere proportion, with hardness, wear resistance and corrosion resistance as the properties characterization. The results shows that C3H8:H2=1:40 have better properties with the hardness of 950 HV0.05, the friction coefficient of about 0.25, which showed a better wear resistance. And also the corrosion rate of about 20.3g/m2·h showed a better corrosion resistance.

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.

The novel low temperature plasma alloying technique that simultaneously introduces both nitrogen and carbon into the surface of austenitic stainless steel has been used in the past to create a hybrid N-C S-Phase. This S-Phase layer boasts of high hardness and wear resistance without any detriment to corrosion resistance. In this study, the afore mentioned hybrid N-C S-Phase was successfully implemented in the surface of two medical grade austenitic stainless steels: ASTM F138 and F1586. At an optimum process temperature of 430°C a very hard, 20μm precipitate-free S-Phase layer was created. Anodic Polarization tests in Ringer’s solution showed that the corrosion resistance of this layer was similar to that of the untreated alloys. Both dry-wear and corrosion-wear (Ringer’s) behaviour of the surface treated alloys showed an improvement of more than 350% and 40% respectively when compared to the untreated material.
