摘要
微弧氧化是一种可在铝、镁、钛等金属表面制备耐热、耐磨、耐腐蚀等特性陶瓷层的表面处理技术。但陶瓷层中固有的孔隙以及有限的相组成被认为是微弧氧化技术亟待解决的难题。为进一步提高陶层的使用性能及扩大使用范围,将功能型微纳米颗粒与微弧氧化技术相结合的方法开始被广泛研究。综述了添加微纳米颗粒的种类、尺寸和浓度对微弧氧化行为、膜层微观结构、相组成、耐磨性能、耐蚀性能的影响,分析了微纳米颗粒与陶瓷层的结合机制,最后指出了该复合技术目前尚待解决的问题,并对该技术在今后的发展趋势和实际应用进行了展望。
Microarc oxidation(MAO)is a surface treatment technology that can produce heat-resistant,wear-resistant,corrosion-resistant ceramic layers on surface of metal such as aluminum,magnesium and titanium.However,the pores inherent in the ceramic layer and the limited phase composition are considered to be the problems to be solved in the MAO technique.In order to furtherly improve the performance and enlarge the range of use of ceramic layers,the combination of functional micro-nano particles and MAO technology were extensively studied.The effects of the type,diameter and amount of micro-nano particles on the MAO behavior,the microstructure,phase composition,wear resistance and corrosion resistance of the layer were reviewed.The combination mechanism between micro-nano particles and ceramic layer was analyzed.Finally,the unsolved problems of the composite technology were pointed out,and the practical application and trend of the technology in the future were prospected.
