| 摘 要： | 在Na2SiO3, (NaPO3)6和NaAlO2溶液体系中制备了铝合金微弧氧化陶瓷膜, 研究了电解液种类和浓度对陶瓷膜相组成和元素成分的影响. 结果表明, 陶瓷膜中α-Al2O3较γ-Al2O3的相对含量受电解液的种类和浓度的影响大. 不同溶液制备的陶瓷膜元素成分不同, 同种溶液制备的陶瓷膜中同种元素在表层和致密层中的含量也有所不同.

| Abstract: | Microarc oxidation coatings on aluminium alloy were prepared in Na2SiO3 and (NaPO3)6 as well as NaAlO2 aqueous solution, and the effects of electrolyte category and concentration on phase component and elementary composition were studied. The experimental results show that the content of α-Al2O3/
γ-Al2O3 is closely relative to electrolyte category and concentration. Elementary compositions of coated samples fabricated in diffe
rent electrolyte solution are different, and the content of same element in surface and density layers of coatings prepared in same electrolyte are also different. |

| Keywords: | aluminium alloy microarc oxidation phase component elementary composition |
