摘　　要：在硅酸钠、钨酸钠、硼酸、偏铝酸钠和乙二胺四乙酸二钠的复合电解液中,利用微弧氧化方法,在ZL102铸造铝合金上制备了陶瓷膜层。结果表明:脉冲电源获得的氧化膜表面由熔化凝固后的氧化物颗粒组成,颗粒呈不规则球形,周围有明显的熔化痕迹,表面粗糙凹凸不平且不均匀。通过对陶瓷膜层能谱分析,膜层中出现了Al、Si、Na、O、W元素。In the composite electrolytes of sodium silicate, sodium tungstate, boric acid, sodium aluminate and ethylenediamine tetraacetic acid disodium, the ceramic layers on the aluminum casting alloy --ZL102 were prepaired using the method of micro--arc oxidation. Results show that the surface of oxidation ceramic layers is rough rugged, uneven and composed of the melt solidified particles, which are irregular roundness and surrounded by obvious signs of melting. Through the energy spectrum analysis, the film contains Al, Si, Na, O, W elements.
