Abstract

Reflecting the broad interest in additive manufacturing (AM), this study focuses on the tribological behavior of 316 L stainless steel against 100 Cr6 alloy under various cooling environments. Tribological experiments were conducted on additively manufactured 316 stainless steel using a ball-on-flat tribometer under dry, minimum quantity lubrication (MQL), cryogenic, and hybrid cryo+MQL conditions. Subsequently, the most critical tribological variables such as friction forces, volume loss, wear depth, and micrographs were investigated. The results revealed that the combination of cryo and MQL cooling conditions are helpful in improving the tribological performance while minimizing material volume loss and wear rates. Cryo+MQL condition shows better performance based on volume loss as 2.33, 11.2 and 14.8 times than MQL, cryo and dry conditions, respectively.
