Investigation of Wear Properties of EBM Processed Ti6Al4V with UHMWPE for Biomedical Applications
The wear of polymeric bearing material in contact with metallic biomedical implant has often been the main cause of long-term clinical failure of such implants. Very few studies seem to have been undertaken to investigate the wear behaviour of Ultra-High-Molecular-Weight-Propylene (UHMWPE) bearing material in contact with titanium alloy implant material under various loading conditions. This research paper presents an investigation on the wear properties of UHMWPE under dry and wet sliding conditions at different loading conditions. In this study, the well-known pin-on-disk equipment was used to carry out the sliding wear test. The titanium pin was made by Electron Beam Melting (EBM) technology and machined to rub on the UHMWPE disk. The aim is to understand the wear characteristics of UHMWPE in relation to Ti6Al4V alloy under various loading and lubricating conditions. Results include volume loss and wear rate analysis.
