综合国内外钛合金微弧氧化生物膜制备的方法，主要阐述了电参数与电解液对钛合金微弧氧化生物膜结构以及性能的影响机制。脉冲电源下，电流对膜层的制备具有良好的调整作用，且得到的膜层厚度显著增大。膜层厚度随氧化电压的升高而增加时，膜层表面颜色与腐蚀电位也发生变化。增加脉宽，降低频率时，单脉冲放电能量随之增加，微弧氧化成膜速率显著加快。不同体系电解液制备的膜层表面粗糙度、微孔结构等存在差异。在电解液中引入银、锌、铜离子能有效改善植入物涂层表面细菌黏附引起的异物炎症问题，增强其抗菌作用。基于目前钛合金微弧氧化的研究进展，展望了该研究方向，对钛合金植入物在临床医学应用发展中具有积极的促进作用。

This paper summarized the preparation methods of micro-arc oxidation biofilm on titanium alloy at home and abroad, and mainly elaborated the influence mechanism of electrical parameters and electrolyte on the structure and performance of micro-arc oxidation biofilm on titanium alloy. The current under the pulse power supply had a good adjustment effect on the preparation of the film, and the thickness of the obtained film was significantly increased. When the film thickness increased with the increased of the oxidation voltage, the color of the film surface and the corrosion potential also changed. When the pulse width was increased and the frequency was decreased, the single pulse discharge energy was increased, and the film formation rate of micro-arc oxidation was significantly accelerated. There are differences in the surface roughness and microporous structure of membranes prepared from different electrolyte systems. The introduction of silver, zinc, and copper ions into the electrolyte can effectively improve the problem of foreign body inflammation caused by bacterial adhesion on the surface of the implant coating, thereby enhancing its antibacterial effect. Based on the current research progress of titanium alloy micro-arc oxidation, this research direction was prospected, and it had a positive role in promoting the development of titanium alloy implants in clinical medical applications.
