摘要

Nano-TiO₂-ZnO composite dispersions were prepared by dispersant dispersing method and adjusting pH, and the dispersions were added to the micro-arc oxidation electrolyte, and the micro-arc oxidized ceramic film layer containing nano-TiO2 and ZnO was prepared on the surface of AZ91D magnesium alloy. The addition concentration of the dispersion was explored, and through the characterization and performance tests, we concluded that the densification, contact angle, hardness, salt solution corrosion resistance, UV corrosion resistance, SBF corrosion resistance, and antimicrobial properties of the film layer were optimized and enhanced to different degrees when the addition amount was 5 g/l.
