Abstract
Hydroxyapatite (HA) coatings doped with different contents of SiC nanowire (SiCnws) were prepared on the surface of AZ31 magnesium alloy by electrophoretic deposition to solve the problems of low adhesion and poor wear resistance of pure HA coatings. Performance tests were conducted on the coating, including corrosion resistance, adhesion and wear performance. The results showed that the prepared coating was intact. The adhesion and wear resistance of the coating were significantly improved when the doping amount of SiCnws was 3%. Among them, the adhesion increased by 37.06% and the scratch depth decreased by 86.67%. At the same time, the corrosion resistance of the coating still maintained a high level. It showed that the performance of doping 3% SiCnws modified coating was balanced and excellent in all aspects.
