“…This research uses homemade DC Glow Discharge plasma for the plasma nitrocarburizing process. In addition, DC glow discharge plasma is also used for plasma nitriding, carburizing, and diamondlike carbon (DLC) coating processes [7]- [11]. Specifications of the equipment used: The dimensions of the reactor tube are 32 cm in diameter and 40 cm in height; the E2M2 rotary pump has a capacity of 2.8 m 3 /hour and a power supply of 2kW [12].…”

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 500°C for 4 hours. The optimum wear resistance or specific wear results on plasma nitrocarburizing was 0.11 x10-6mm2/kg at temperatures 400°C for 4 hours and 0.08 x10-6mm2/kg at temperature 500°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.

Plasma nitriding (also known as ion nitriding, plasma ion nitriding, or glow-discharge nitriding) is a method of surface hardening using glow-discharge technology to introduce nascent (elemental) nitrogen to the surface of a metal part subsequent diffusion into the material. Because of the formation of high compressive residual stresses in the case region, increasing surface hardness and depth parameters cause remarkable improvement in the mechanical properties of steels. In this study, the properties of a nitrided local disc brake were investigated. For that purpose, the material was nitrided at 400°C of temperature, 1.6 mbar of pressure, and 4 hours of time then followed by post-treatment in Argon (Ar) environment for various of holding time such as 10, 20, 30, 40, and 50 minutes. At these conditions the hardness increased in the range 123.1 -223.3 VHN, the wear rate decreased in the range 21.7 × 10 -9 -3.1 × 10 -9 mm 3 /mm kg, while before being nitrided the hardness and the wear rates were 113.5 VHN and 22.8 × 10 -9 mm 3 /mm kg, respectively. The optimum condition for holding time during post treatments was 20 minutes. Besides that, the effect of various of N 2 : Ar mixture such as 90%: 10%, 80%: 20%, 70%: 30%, and 60%: 40% on the properties of local disc brake was studied. For various of gas mixing, the optimum hardness in the order of 252.7 VHN and wear rate in the order of 2.8 × 10 -9 mm 3 /mm kg were achieved at 90%N 2 : 10%Ar of a gas mixture.
