微弧氧化技术是近年来在国内兴起的铝及其合金的新型阳极氧化技术。通常 ,微弧氧化是在阳极氧化膜被电击穿的基础上进行 ,电击穿理论的研究有利于表面处理新技术的开发及微弧氧化机理的探讨。在此总结了几十年来电击穿理论的研究成果 ,并对各种理论假设和模型进行了评价。 Micro-arc oxidation technology in recent years in China and the rise of the new aluminum and its alloys anodizing technology. Generally, micro-arc oxidation is carried out on the basis of anodic breakdown of the anodic oxide film. The study of electro-breakdown theory is conducive to the development of new surface treatment technology and the micro-arc oxidation mechanism. Here we summarize the research results of the theory of electric breakdown in decades, and evaluate various theoretical hypotheses and models.
