Abstract:: Micro-arc oxidation is an effective surface treatment technology to enhance the biocompatibility and antibacterial activity of titanium implants. The preparation of porous coatings composed of bioactive elements on the surface of titanium implants is the most attractive feature of micro-arc oxidation technology. Herein the basic principle of micro-arc oxidation is mainly introduced; the technical advantages of the technology are expounded; and the research progress of several kinds of micro-arc oxidation coatings at home and abroad is summarized. The osteointegration, antibacterial activity and toxicity of micro-arc oxidation coatings containing calcium and phosphorus, silver, copper, zinc, and silicon are emphasized. The review provides a more comprehensive perspective for researchers to evaluate the progress of micro-arc oxidation technology in orthopaedic titanium implants, providing some reference for further clinical research.
