摘要
采用微弧氧化技术在2A12铝合金表面制备出不同厚度的陶瓷层,测试了该陶瓷层在纯滚动摩擦条件下的摩擦磨损性能。结果显示:在滚动摩擦条件下,陶瓷层失效形式受到其厚度的影响,当陶瓷层厚度小于临界厚度时,试样表面出现陶瓷层剥落现象。结合疲劳理论,对该失效形式进行了分析与研究。
Ceramic layer with different thickness was fabricated by micro-arc oxidation on the surface of 2A12 Al alloy, and the ceramic layer＇ s wear-resistant property was tested on the condition of rolling friction. Results showed the type of ceramic layer＇ s wears failure was affected by ceramic layer＇s thickness under this friction condition; while the ceramic layer would desquamate if its thickness was less than the critical numerical value. Basing on the fatigue theory, we investigated this failure type.
