Effect of elevated temperature on wear performance of laser powder bed fusion fabricated SS316L

In the field of additive manufacturing, Laser Powder Bed Fusion (LPBF) has become a good technique for manufacturing metallic parts. The aim of this investigation was to clarify how temperature, sliding speed, and load affected the tribological properties of SS316L that was made by LPBF. Test temperature, sliding velocity, and applied load all had a significant impact on sample wear rate as well as their Coefficient of Friction (COF), according to the data. Particular note: at a test temperature of 250 °C, wear rate and COF showed lower values compared to ambient temperature data. The oxide layer formed on the surface that served as a lubricant and reduced material deterioration. Moreover, increased normal loads and decreased sliding velocities were associated with an increasing trend in both COF and wear rate.
