氧化时间对7A09超高强铝合金微弧氧化陶瓷膜的影响
Effects of Oxidation Time on Micro-arc Oxidation Ceramic Coatings of Super-high-strength Aluminum Alloy 7A09
摘要
Abstract
In sodium aluminate and sodium hydroxide system, the micro arc oxidation was used to 7A09 super-high strength aluminum alloy. The influence of oxidation time on ceramic layer thickness, micro hardness, surface and cross-section morphology and phase composition was studied. The results show that, in the condition of the same other parameters constant, with the micro arc oxidation time being 45 minutes, the highest micro hardness of Ceramic layer is 1070HV0. 1 , and the ceramic layer mainly consists of γ-Al2O3.关键词
