Abstract

The current study addresses the tribological characteristics of Cast Polyamide 6 (PA 6 G) matrix and its composite filled with polyethylene (PE) solid lubricant (PA 6 G SL). Tribological tests under different contact kinematics (1) traditional pin-on-disc (PoD) and (2) dynamic pin-on-plate (PoP). Tribotests revealed that the PA 6 G SL composite showed increased wear resistance and reduction in heat generation as compared to the virgin PA 6 G matrix. The difference in tribological characteristics was analyzed with respect to morphology (primary and secondary layer) of the transfer layer formed on the counter material. In summary, the solid lubricant alters the tribological process by means of altering the surface response by introducing a limitation in the wear particle generation.
