Load-Dependent Frictional Performance of Vitamin E-Blended Ultrahigh Molecular Weight Polyethylene in Serum Lubricant

Tribology Online, 2010
The load-dependent frictional performance of vitamin E-blended ultrahigh molecular weight polyethylene (UHMWPE) in serum lubricant was examined. The UHMWPE specimens were slid against the surface of Co-28Cr-6Mo alloy by using a pin-on-disk friction test ...
