Abstract

This study observed the results of plasma nitrocarburizing processes on JIS SKD61 Steel. This research aims to use a plasma nitrocarburizing process to increase the hardness and wear resistance of JIS SKD61Steel. Before plasma nitriding was carried out, the sample had undergone a pre-treatment process. The optimum hardness value obtained after the pre-treatment process was 504 HV. The optimum hardness obtained in the plasma nitrocarburizing sample was 830 HV at temperatures 500o C for 4 hours. The optimum wear resistance or specific wear results on plasma nitrocarburizing was 0.11 x10-6 mm2 /kg at temperatures 400o C for 4 hours and 0.08 x10-6 mm2 /kg at temperature 500o C for 4 hours. XRD test results show that the phase formed in the nitrocarburizing compound layer was the iron nitride, iron carbonitride FeN, FeN0.49, ε-Fe2-3N, or ε-Fe2-3(N,C) . The process of plasma nitrocarburizing has improved the mechanical properties of hardness and wear resistance of SKD61 steel.
