Abstract

The wear resistances of AZ91D magnesium alloy with and without microarc oxidation (MAO) coating andTi6Al4Valloy in artificial saliva were investigated at room temperature. The wear resistance of AZ91D magnesium alloy in artificial saliva was significantly improved after microarc oxidation treatment. The volume loss of untreated AZ91D magnesium alloy sample was 20.95 times of that of AZ91D magnesium alloy with MAO coating, and that ofTi6Al4Vwas 5.42 times of that of MAO. Furthermore, the wear resistance of AZ91D magnesium alloy was lower than that ofTi6Al4Valloy in artificial saliva. The wear mechanisms of AZ91D magnesium andTi6Al4Vwere discussed. It was found that the wear mechanism of the MAO was associated with abrasion and microfracture. There were two dominative wear mechanisms for AZ91D alloy andTi6Al4Valloy under the loading conditions used in the experiment, namely, micro-machining wear and deformation-induced wear.
