| 中文摘要: |
| 微弧氧化(MAO)又称为微等离子体氧化(MPO)、阳极火花沉积(ASD)或火花放电阳极氧化(SDAO)，它是一种直接在有色金属表面原位生长陶瓷膜层的表面处理新技术。该技术突破了传统阳极氧化的诸多不足之处，通过对工艺过程的控制，可以使金属表面陶瓷化，生成的陶瓷薄膜具有优异的耐磨和耐蚀性能、较高的硬度和绝缘电阻。基于目前微弧氧化技术在Al、Mg、Ti及其合金表面改性方面的广泛应用和进展，综述了微弧氧化技术的工艺原理、技术特点、微弧氧化膜层的性质和影响因素以及该技术的应用现状。 |
| 英文摘要: |
| Micro-arc oxidation ( MAO) , also called micro plasma oxidation (MPO)/ anodic spark deposition ( ASD)/spark discharge anodic oxidation ( SDAO) , allows the deposition of in situ ceramic oxide coating on the surfaces of nonferrous alloys. The process overcomes some shortcoming of the traditional anodic oxidation process by combining electrochemical oxidation with a high voltage spark treatment. The formed ceramic coating with excellent anti-wear, anticorrosion, high hardness and good insulation can make the metal behave as ceramic materials through adjustment of the process. Based on the extensive application and development of micro-arc oxidation on nonferrous metals, such as Al, Mg, Ti and their alloys, the mechanism and properties of this technology, the properties of the micro-arc oxidized film and its influencing factors were reviewed. In addition, the application status and development prospect were analyzed based on employment of this technology on the nonferrous metals and their alloys. |
