摘要
微弧氧化是一种新型的表面处理方法,正成为材料表面工程技术领域的一个研究热点。微弧氧化电源是制约该技术发展和应用的关键因素之一,直接影响微弧氧化膜层的性能。目前,采用不对称的交流或双向不对称脉冲工作模式的电源是微弧氧化技术的重要发展方向。介绍了微弧氧化电源的发展情况和国内微弧氧化电源的研究现状,简要概括了国内研制的包含有双向不对称脉冲输出功能的几种典型电源型式,并对两级逆变式电源和其他型式的电源进行了比较。
MAO is a new method of surface treatment,and it is becoming an international research focus of Surface engineering and technical field.MAO Power Supply is one of the most important facts for its development and application,and impacts the ceramic film directly.At present,asymmetrical AC and pulse with two polarities mode power supply is an important developing direction of the technology.This paper introduced the development and domestic status of research on MAO power supply,then briefly summarized several typical power supplies which contain asymmetrical pulse with two polarities output function,furthermore,compared the twice-inverter power supply with others.
