The paper discusses in detail the tribological properties of Selective Laser Melting (SLM) manufactured Inconel718 using a pin-on-disc tribometer. Inconel with γ′ and γ″ phases is an age hardenable alloy, tailoring suitable phases can improve tribological properties. Homogenization heat treatment that had been done according to the AMS 5662 procedure, the micro hardness of the as-built sample which had the least hardness range increased by 69.79% due to the influence of γ and γ″ phases after homogenization heat treatment. The tribology of as-built samples and the samples after heat treatment is evaluated at room temperature to establish a relationship between the microstructural evolution and tribological properties of Inconel718.
