Abstract:
      To improve the bioactivity of surface of titanium and reduce infection rate of implantation, the porous coatings were prepared by ultrasonic micro arc oxidation (UMAO) and Rhizoma drynariae(ERD) coupled by phytic acid .Besides, the structure, surface morphology and performance were investigated. The results indicated that nanoSparticles of drug loading increased with concentration of ERD. The surface of coatings produced PO43-,P2O74- and O=P-O-. The friction coefficient of 12.5 g/L was lower .Also, the coating of 12.5 g/L had a better binding force and was hydrophilic. The potential increased by 0.33-0.45V and self-corrosion current decreased by a order of magnitude for concentration of 12.5 g/L. In conclusion, the corrosion resistance, binding force and bioactivity are improved by drug loading coupled with phytic acid after MAO on the magnesium.
