Pulse width rectifying method, adopted in the power supply using for anodizing process, is proposed. This method needs low requiring voltage and short processing time than previous anodizing method to make a same thickness of Al2O3 layer. The performance test is conducted with power supply using the pulse width rectifying method. The aluminum specimen having Al2O3 layer generated by proposed anodizing process is analyzed by using the SEM image. From the analysis of SEM image, the generation rate of Al2O3 layer is calculated as 1.25μm/min.
