| 摘 要： | 采用微弧氧化技术在铝合金上合成了陶瓷膜， 研究了阳极电流密度和阴／阳极电流密度比对陶瓷膜特性的影响. 结果表明， 阳极电流密度对陶瓷膜中α-Al2O3比γ-Al2O3的相对含量影响很大， 但阴／阳极电流密度比对其相对含量的影响较小， 而陶瓷膜的显微硬度、 微观结构和致密层的厚度与阳极电流
密度和阴／阳极电流密度比密切相关.

| Abstract: | Ceramic coatings on aluminium alloy were prepared by means of microarc oxidation (MAO) technique, and the effects of anodic current density and the ratio of cathodic current (jc) density to anodic current
density (ja) on the properties of the coatings were studied. The experimental results show that the content of α-Al2O3/γ-Al2O3 is closely relative
to ja but the effect of jc/ja on the phase con
tent is unobvious. However, microhardness and microstructure as well as the density thickness of the coatings have something to do with ja and jc/ja. |
