Abstract

This research investigates the tribological characteristics of SS316L produced through Laser Powder Bed Fusion (LPBF), emphasizing the influence of testing temperature, sliding velocity, and loading conditions. The findings demonstrate that the friction coefficient escalates with increased temperatures (150°C and 250°C), whereas the wear rate remains invariant, presumably attributable to the establishment of a lubricating surface layer. The rotational velocity of 300 revolutions per minute the Coefficient of Friction (COF) shown an upward movement although the wear rate remains constant. The findings underscore the importance of analyzing different parameters to understand the friction and wear properties of additively manufactured SS316L.
