Abstract:
      The chitosan interlayer was formed on ultrasonic micro-arc oxidation(UMAO) coating of pure magnesium by electrophoretic deposition technique, on which we employed immersion method to make coatings with chinese herbal extract. Influence of chinese herbal extract on microstructure, tribological properties, corrosion resistance and biological activity of the composite coatings was investigated. The results show that UMAO coating is sealed by coatings with chinese herbal extract. The corrosion resistance of the coatings with chinese herbal extract is increased with appropriate surface condition. The binding force and tribological properties of the coating with chinese herbal extract are increased under chemical binding. The coatings with chinese herbal extract also has shown better biological activity invitro.
