摘　　要：在电解液中添加不同浓度的氧化亚铜微粒,然后在TC4钛合金表面制备掺杂铜氧化物的微弧氧化层。在模拟海水中进行微弧氧化层的摩擦磨损和抗菌实验,并使用扫描电镜(SEM)、X射线衍射仪(XRD)、X光电子能谱仪(XPS)和显微硬度仪等手段对比研究了掺杂氧化亚铜的微弧氧化层的微观结构和性能。结果表明:掺杂氧化亚铜的微弧氧化层表面呈多孔形貌特征,但是微孔的数量较少和孔径尺寸较小,氧化亚铜微粒在膜层中以氧化铜和氧化亚铜两种形式存在;与未掺杂氧化亚铜的微弧氧化层相比,添加不同浓度氧化亚铜的微弧氧化层在模拟海水中的抗磨损性能和抗菌性能显著提高,但是微弧氧化层中的铜元素使其耐蚀性有所降低。The microarc oxidation coating doped with coprous oxide was prepared on the surface of TC4 Ti-alloy by adding different amount of cuprous oxide particles into the electrolyte.The microstructure and properties of the cuprous oxide doped microarc oxidation coating were investigated by means of scanning electron microscope(SEM),X-ray diffractometer(XRD),X-ray photoelectron spectroscope(XPS)and microhardness tester.The results show that the surface of the microarc oxidation coating doped with cuprous oxide is porous,but the number and size of micropores are small.However the doped Cu oxides are present in the coating in two forms,namely copper oxide and cuprous oxide.Compared with the microarc oxidation coating without doping of cuprous oxide,the wear resistance and antibacterial performance of microarc oxidation coating doped with different amount of cuprous oxide are significantly improved in artifitial seawater,but their corrosion resistance degraded.
