Abstract: HA coatings with silver-zirconium phosphate antimicrobial were prepared via vacuum plasma spraying, and then their surface morphologies, phase compositions, bonding strengths and antibacterial capability were examined. The results obtained show that no obvious change of the surface morphologies is observed after adding antimicrobial in HA coatings. Some new phases such as CaZr(PO4)2 and Na6CaP2O9 appear in the coatings when the antimicrobial
content is high to 10wt%. The bonding strengths of the HA coatings with antimicrobial are higher than that of the HA coating, and the values increase with the increase of antimicrobial content in the coatings. The coatings with the content of antimicrobial equal to or higher than 5% are effectively antibacterial to Pg, Fn and Aa. The antibacterial ability is ordered as Pg>Fn>Aa.

Key words: vacuum plasma spray, HA coating, antibacterial, silver-zirconium phosphate antimicrobial
