Wear of Ultra-High-Molecular-Weight-Polyethylene Sliding against a CoCrMo Coating applied by Physical Vapour Deposition

Funded under: FP5

Abstract

In this study, the wear behaviour of UHMWPE (Ultra-High-Molecular-Weight-Polyethylene) sliding against a cast CoCrMo alloy, a forged CoCrMo-coating obtained by Magnetron Sputtering Physical Vapour Deposition (PVD) was investigated. The results show that the UHMWPE wear was least for the cast CoCrMo and the forged CoCrMo alloys, whereas the CoCrMo-PVD coating caused significantly higher UHMWPE wear. It is assumed that this high wear is due to the delamination of small parts of the coating during the test, leading to the formation of a large number of microscratches and ridges, which increase the surface roughness.
