Abstract

Wear of ultra-high molecular weight polyethylene (UHMWPE) has been recognized as the main cause for long-term revision in joint arthroplasty. A new approach to overcome this detrimental issue is here presented: zirconia (ZrO2) thin films were directly deposited onto the surface of UHMWPE by Pulsed Plasma Deposition (PPD) technique. The obtained films were structurally, morphologically and mechanically characterized by X-ray diffraction, scanning electron microscopy and nanoindentation tests, respectively. The critical fracture load was estimated by the analysis of the indenter footprints, while the adhesion degree was evaluated by a cross-cut tape test. Zirconia films exhibited a fully cubic structure, with densely packed grains, whereas mechanical tests showed that hard, tough and well-adherent films were deposited. These preliminary results suggested the feasibility of pursuing this alternative route to improve UHMPWE performances while preserving its well-established mechanical properties. © 2013 The Royal Society of Chemistry.
