摘要
随着微弧氧化技术及其工业应用的发展,作为关键设备的电源对微弧氧化的影响得到了广泛的关注。综述了电源特性和参数对膜层性能以及工艺能耗影响方面的研究,总结了电源工作模式和电流密度、电压、频率等电参数对膜层相组成、表面形态、耐蚀性等性能以及工艺能耗的影响规律,指出电源特性和参数的影响本质上是电源脉冲能量的影响,能精确控制脉冲能量的电源是今后的发展方向。
Power supply is one of the key equipments of micro-arc oxidation（MAO） treatment, and it has important influence on MAO. This paper reviewed the effects of characteristic and parameters of power supply, such as controlling modes, current density, voltage, frequency and so on, on the property of MAO coatings, such as phase composition, surface morphology, and corrosion resistance and so on. In addition, the influences of power supply on the energy consumption of MAO treatment were summarized. It was revealed that the effects of characteristic and parameters of power supply are essentially the effects of discharging energy of a single pulse. The power supply which could accurately regulate pulse energy will be the research emphasis.
