摘　　要：介绍了微弧氧化技术在钛合金耐磨、耐蚀、生物涂层、电子涂层方面的研究及应用现状。微弧氧化技术制备的陶瓷涂层具有硬度高、致密的特点,提高了基体的耐磨、耐蚀性能;通过调整溶液组分,获得具有高生物活性的生物涂层和电子涂层等功能涂层。目前钛合金微弧氧化涂层的研究尚处于起步阶段,但研究表明微弧氧化技术在改善钛合金的使用性能方面具有广阔的应用前景。Microarc oxidation is a new technique, which can form the in-situ ceramic coatings on the surfaces of some non-ferrous metals. This paper reviews the applications of MAO in wear resistance, corrosion , medicine film and electronic film on titanium.It shows that the MAO coatings have high hardness and density, which can increase the wear resistance and corrosion of substrate. Functional coatings of high biological activity or electronic can be obtained by different electrolyte. This technique has good prospect in improving the performance of titanium alloy.
