摘要：

Friction and wear tests have been performed on ultra-high molecular weight polyethylene (UHMWPE) in presence of proteins, dry sliding conditions against a steel counterface disc and the results have been analyzed in detail. UHMWPE was found to exhibit lowest friction coefficient and wear rates when lubricated with bovine or globulin and with bovine albumin respectively. Post-test analysis of the proteins indicated denaturing, formation of reaction products of specimens and proteins. The predominant wear mechanisms found were adhesion, abrasion and fatigue.
