摘要
介绍了直接复合技术和二次复合技术即微弧氧化与后处理技术(溶胶凝胶技术、化学镀、电泳涂装、热喷涂、磁控溅射技术等)相结合的研究现状。综述了两种方式对形成的复合膜层微观形貌、力学性能、耐蚀性能等方面的影响。对膜层直接进行复合处理,添加颗粒直接参与了反应过程,成为复合膜层中的一部分,对膜层微观结构和形貌都产生了一定程度的影响。在减小孔隙率和微裂纹使致密度增加的同时,膜层的耐蚀性和耐磨性均得到了提高;而对膜层进行二次复合处理,增加耐蚀性的同时也可能会造成力学性能下降。
Direct composite technology and secondary composite technology that micro-arc oxidation combined with post processing technologies（sol-gel technology,electroless plating,electrophoresis,plasmas spraying,magnetron sputter ion plating）were introduced.Influences of different composite technology on microstructure,mechanical properties,corrosion resistance of the composite membrane layer were expounded.Through direct composite treatment,different particles added takes as a part of the composite membrane layer through directly joining the reaction process,affecting the microstructure and morphology of the composite membrane layer to some extent,and besides of improving compactness by decreasing porosity and micro-crack of the membrane layer,the corrosion resistance and wear resistance are improved.Secondary composite treatment can increase the corrosion resistance and decrease the mechanical properties.
