Abstract

Joint prosthesis are usually subjected to several failing mechanisms, including wear of the ultra-high molecular weight polyethylene (UHMWPE) insert. The main goal of this study was to assess the possibility to improve the tribological properties of titanium component by depositing zirconia thin films on its surface by pulsed plasma deposition (PPD) method. Zirconiacoated titanium spheres were tested against UHMWPE disks, both in dry and wet conditions. Zirconia films exhibited a homogenous sub-micrometric grain size distribution and low roughness. Interestingly, zirconia-coated titanium spheres showed lower wear rate of the UHMWPE component, compared to uncoated titanium spheres, supporting the feasibility of the proposed approach.
