摘　　要：在传统ZL101铸造铝硅合金的基础上,通过添加Cu、Ni、Mn、V、RE等合金元素,研制了改良铸造铝硅合金,并对该改良合金常温(25℃)下在酸、碱、盐腐蚀介质中的耐腐蚀性能进行了研究。研究结果表明,常温下在酸、碱、盐腐蚀介质中,改良铸造铝硅合金耐腐蚀性能均优于ZL101合金。On the basis of traditional ZL101 casting aluminum-silicon alloy, by adding alloying elements such as Cu, Ni, Mn, V, RE, a modified casting A1-Si alloy was developed, and the corrosion resistance of the improved alloy at room temperature （25℃） under acid, alkali and salt solutions were studied. The results show that the corrosion resistance of the improved casting aluminum-silicon alloy at room temperature under acid, alkali and salt solutions is superior to ZL 101 alloy.
