Sliding wear behavior of sintered alumina with grain sizes between 0.45 and 4 microm was studied in bovine serum environment with unidirectional pin-on-disc wear testing machine. Submicron grained alumina of average grain size of G=0.45 microm exhibits lowest wear factor among the others. It was found that grain pull out or localized grain dislodgement(More)
