dc.description.abstractThe ceramic films over metallic implant surfaces have-the potential to improve implant performance with respect:to implant fixation, wear, or corrosion. In this study, the electrolytic Al2O3 coatings on 1-1537 Co-Cr-Mo alloy were conducted in an aqueous solution of Al(NO3)(3). Through the cycle polarization test in Hank's solution, it was found that the corrosion potential and protection potential of the alumina-coated were higher than that of the uncoated, and the corrosion current density was lower. The phase transformation of Al2O3 film on Co-Cr-Mo alloy annealed at 800 K revealed todlite (5Al(2)O(3) . H2O) and theta Al2O3 (113) preferred orientation for 20 min, and theta Al2O3 (200) preferred orientation with eta phase for 80 min. Scanning electron microscopy/energy dispersive spectroscopy observations after the scratch tests showed that the adhesion of the alumina films on Co-Cr-Mo alloy can load a stress over the yield strength (450 MPa) of Co-Cr-Mo alloy. The wear loss of ultra-high molecular-weight polyethylene to the Al2O3-coated specimen was eight times less than that to the uncoated. It is concluded that such Al2O3-coated films on Co-Cr-Mo implant alloy exhibit excellent quality in corrosion, adhesion, and wear for the application of hip prosthesis.
