摘　　要：微弧氧化是一种能有效提高锆合金耐蚀性的工艺手段。采用三种不同电解液体系制备出锆合金微弧氧化膜层,采用显微硬度计、XRD、EDS、SEM分别分析了陶瓷膜层的硬度、相组成、元素分布和表面形貌。结果表明:在硅酸盐体系中制备的陶瓷膜硬度最高,锆盐体系试样硬度最低。XRD分析表明,在三种电解液体系中制备的陶瓷膜的主要相均为M-Zr O2和T-Zr O2,并且M-Zr O2居多,但在锆盐体系中制备的膜层发生局部腐蚀。The micro-arc oxidation is an effective process for improving the corrosion resistance of zirconium alloys.Three different electrolyte systems are used to prepare the micro-arc oxidation film of zirconium alloy.The hardness,phase composition,element distribution and surface mor-phology of the ceramic film is analyzed by the microhardness tester,XRD,EDS and SEM respectively.The results show that the ceramic film pre-pared in the silicate system has the highest hardness,and in the zirconate system has the lowest hardness.The XRD analysis show that the main phases of the ceramic films prepared in the three electrolyte systems are M-ZrO2 and T-ZrO2,and the M-ZrO2 is in the majority,but the films prepared in the zirconate system undergo a localized corrosion.
