摘要(Abstract)：

采用控制变量、正交试验法,通过测定膜层厚度、截面显微硬度、表面粗糙度、表面形貌、截面形貌及摩擦磨损试验、膜层表面XRD的分析对制备ZL109铝合金微弧氧化陶瓷层的电解液组成及电参数进行了优化研究。得到了制备ZL109铝合金微弧氧化耐磨陶瓷层的一组优化后的工艺方案,电解液配方为:8 g/L硅酸钠、2.5 g/L氢氧化钾、5 g/L钨酸钠、2 g/L乙二胺四乙酸二钠;电参数为:正向电压400 V、负向电压120 V、占空比20%、频率500 Hz。所生成的膜层厚度为76μm,表面粗糙度为2.2872μm;摩擦磨损试验中,磨损状态稳定,磨损量在30 h后稳定在1 mg左右。
