| 摘 要： | 微弧氧化又称阳极火化沉积技术或等离子体增强电化学陶瓷化技术。该技术生成的膜与基体金属结合牢固，厚度可达230μm，绝缘电阻大于100MΩ，硬度达2500HV，大大改善了轻金属的耐磨性、耐蚀性和耐热冲击性，工件尺寸变化小。本文研究在铝合金表面微弧氧化制备陶瓷化氧化膜，以期改善铝合金的耐磨特性。讨论了影响制备陶瓷弧氧化膜的主要因素。

| Abstract: | Microarc oxidation,is called by anodic oxidation,or plasma enhanced electrochemical surface ceramic coating technology.The films formed on the metal combine with the substrate firmly,are up to 230 μm thick.Its dielectric resistor is 100 MΩ,and microhardness is up to 2500 HV.These properties better the wear resistance,corrosion resistance and thermal property of the light metals.The work piece changes little in size.The paper studied the ceramic coating was attempted to prepare on the surface of the aluminium alloy by microarc oxidation to improve its abrasion resistance.The major factors affecting the vifreous films were discussed. |
