Abstract

In this study, the Ti-6Al-4V alloy will be undergo the gas nitriding process in order to enhance its surface properties. Ti-6Al-4V is widely used in industries due to its beneficial properties but its applications is restricted by its poor tribological properties. Hence, the gas nitriding is the most common effective surface treatment process to enhance the tribological properties of Ti-6Al-4V. In gas nitriding process, the process temperature and time are the crucial parameters that may affected the desired surface properties obtained. Based on the literature review, this study has proposed the process temperatures which are 650 °C, 750 °C and 850 °C carried out for the process time of 2 and 4 hours respectively. After the gas nitriding process, the surface properties analysis which include microstructure analysis, surface roughness analysis and hardness analysis is conducted to observe the surface properties of the nitrided samples in comparison with the reference sample which refer to the untreated Ti-6Al-4V.
