中文摘要：

AM60B 镁合金上的氧化物涂层用微弧氧化(毛) 被准备在有 0-6.0 g/L Na2WO4 的增加的 silicate-KOH 电解质的技术。在有 Na2WO4 的不同集中的基础电解质的毛进程被学习。微观结构，作文和氧化物涂层的机械 tribological 特征被分别地测试的 SEM， XRD， XPS，微坚硬分析和 ball-on-disc 磨擦也调查。进基础电解质的 Na2WO4 的增加在电压的特征上有直接效应，这被发现—在毛过程的时间曲线和击穿电压。在涂层表面的顶的微毛孔的数字被 Na2WO4 的增加增加。在氧化物涂层的 forsterite Mg2SiO4 的部分与在基础电解质增加 Na2WO4 的集中增加。而且，微坚硬并且穿氧化物涂层的电阻也被提高。

英文摘要：

Oxide coatings on AM60B magnesium alloy were prepared using the microarc oxidation（MAO） technique in silicate-KOH electrolyte with addition of 0-6.0 g/L Na2WO4. The MAO processes in base electrolyte with different concentrations of Na2WO4 were studied. The microstructure, compositions and mechanical tribological characteristics of the oxide coatings were also investigated by SEM, XRD, XPS, microhardness analysis and ball-on-disc friction testing, respectively. It is found that the addition of Na2WO4 into the base electrolyte has direct effect on the characteristics of voltage-time curves and breakdown voltage in MAO process. The number of micropores at top of the coating surface is increased by the addition of Na2WO4. The fraction of forsterite Mg2SiO4 in the oxide coating increases with increasing concentration of Na2WO4 in base electrolytes. Furthermore, the microhardness and wear resistance of oxide coatings are enhanced as well.
