Abstract: Anodizing is an effective method to improve the corrosion resistance of magnesium alloys, and the selected electric parameters have great effects on the properties of anodic coatings. Concepts of some electric parameters such as frequency, duty cycle, current density and final voltage were introduced and the relation between duty cycle and current density was deduced. In addition, the research progress about the effects of electric parameters on coating properties was reviewed. With the wide use of electric technology on anodizing power supply, the development trend of anodizing equipment is the intelligence and higher and higher frequency.
Key words: magnesium alloys; anodization; electric parameters; property
