Abstract
The effect of four amide compounds used as additives in liquid paraffin on the friction and wear behavior of steel-steel and steel-aluminum alloy systems was investigated with a four-ball machine and an Optimol SRV friction and wear tester, respectively. The worn surface of the 2024Al alloy block was analyzed by means of X-ray photoelectron spectroscopy (XPS). The results indicate that the four amide compounds used as additives can decrease the wear rate and the friction coefficient of steel-steel frictional pair; acrylamide and acetamide show better anti-wear and friction-reduction ability for the steel-aluminum frictional pair. The XPS analysis of the worn surface of Al alloy block indicates that acrylamide used as an additive in liquid paraffin can decrease the friction and wear of steel-aluminum frictional pair by forming a complex protection film on the worn surface of the Al alloy.
