Material removal during the sliding of hydroxyapatite against UHMWPE.

Abstract:

Hydroxyapatite has been rubbed against ultra-high-molecular-weight-polyethylene (UHMWPE) under calcium-containg aqueous solutions. Further, hardness tests were carried out in air and in calcium-containing solutions whose pH ranged from pH 5 to pH 9. Hardness was found to vary with pH with a peak at around pH 7, i.e. - a chemomechanical effect was observed. Wear tests consisted in sliding hydroxyapatite samples against a UHMWPE disk for eight hours when lubricated by the same solutions as thos...
