| 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。 |
| 关 键 词： | 微弧氧化复合膜层 二氧化锆 硬度 耐蚀性 |

| Abstract: | In this paper, aluminum is used as substrate and micro-arc oxidation (MAO) films are prepared on pure aluminium in the electrolyte with ZrO2 particles. The surface morphologies and composition of micro-arc oxidation composite film are investigated by means of SEM and EDS. This paper studies the effects of nano-particle ZrO2 added in micro-arc oxidation composite film on the microhardness and corrosion resistance of the film. The results show that the surface of micro-arc oxidation film and its composite membrane are rough, and that the ZrO2 nano-particles which are added in the film can reduce crack, decrease pore size, and improve the microhardness and corrosion resistance of the micro-arc oxide film. |
| Keywords: | micro-arc oxidation composite film ZrO2 particles hardness corrosion resistance |
