摘要
Non-uniform microstructure and low growth rate of ceramic coatings in the mid-to late period of micro-arc oxidation (MAO) are the problems that limit the development of micro-arc oxidation technology. In this paper, the MAO process on 6061 aluminum alloy was carried out under ultrasonic condition, and the effects of ultrasonic vibration on microstructure and growth characteristics of MAO coatings were investigated. The results showed that the ultrasonic action obviously promoted the formation of alpha-Al2O3 phase, reduced the number of large discharge pores and promoted the increase of the thickness, uniformity and hardness of the coatings. A concept, breakdown resistance, was defined to discuss the results conveniently. (c) 2013 Elsevier Ltd. All rights reserved.
