The effects of different oxidation voltage and pulsedfrequency on microstructure, thickness and phase constitute of the coatings have been investigated.
试验研究了不同微弧氧化电压和脉冲频率对涂层微观形貌，涂层厚度及相组成的影响。

These include high-pressure processing, pulsed electric fields, radio-frequency electric fields, ultraviolet light, and irradiation.
这些技术包括高压处理，脉动电场，射频电场，紫外线和辐射处理。
