Screening Wear Tester vs. Hip Joint Simulator: Results on UHMWPE sliding against three different CoCrMo Counterfaces
In this study the wear of Ultra-High-molecular Weight Polyethylene (UHMWPE) was investigated using a Reciprocating Pin-on-Flat machine (RDOF) and a hip joint simulator (HIS). The wear couples consisted of UHMWPE and three different CoCrMo surfaces: a standard forged CoCrMo alloy, which underwent two different polishing treatments, and a CoCrMo coating applied by magnetron sputtering physical vapor deposition (PVD). The results show that in the RPOF tests the PVD coating caused significantly higher UHMWPE wear compared to the forged CoCrMo alloy. In the HIS the ranking of the CoCrMo counterfaces with respect to UHMWPE wear was found to be the opposite.
