摘要
以纯铝为基材,在微弧氧化电解液中添加不同含量的纳米ZrO2颗粒进行微弧氧化,制备了ZrO2复合微弧氧化膜层。采用SEM和EDS观察并分析微弧氧化复合膜层表面形貌和膜层成分,研究不同含量纳米ZrO2颗粒的添加对微弧氧化复合膜层硬度和耐蚀性的影响。结果表明,微弧氧化膜及其复合膜层表面粗糙不平,纳米ZrO2颗粒的添加使得微弧氧化复合膜层裂纹减少,孔径减小,硬度和耐蚀性提高。
In this paper, aluminum is used as substrate and micro-arc oxidation （MAO） films are prepared on pure aluminium in theelectrolyte with ZrO2 particles. The surface morphologies and composition of micro-arc oxidation composite film are investigated bymeans of SEM and EDS. This paper studies the effects of nano-particle ZrO2 added in micro-arc oxidation composite film on themicrohardness and corrosion resistance of the film. The results show that the surface of micro-arc oxidation film and its compositemembrane are rough, and that the ZrO2 nano-particles which are added in the film can reduce crack, decrease pore size, and improvethe microhardness and corrosion resistance of the micro-arc oxide film.
