Reconstruction of parts using direct laser deposition can create a combination of high wear resistance properties, good toughness, and corrosion resistance. In this research, the wear properties of Inconel 625 powder cladding on the same substrate have been investigated; For this purpose, room temperature and high temperature wear tests have been used. Mass reduction, friction coefficient, width and depth of wear penetration have been measured. Also, a scanning electron microscope with an energy disspersive spectroscopy system was used to evaluate the cladding surface. The results showed that the mass reduction due to wear at Inconel 625 cladding compared to Inconel 625 substrate has decreased by 7% and 52%, respectively, at temperatures of 25°C and 620°C. Also, the wear mechanism of the room temperature of the cladding is mainly scratchy, and the wear mechanism of high temperature is mainly sticky.
