Modification of ZL107 aluminum alloy has been successfully achieved by using La2O3.The different casting parameters,including casting temperature as well as holding time and modifier content,were carried out to investigate the modification effects.The results show that the best modifier content is 1.0 wt.%,and the casting temperature has little effect.In addition,the wear behavior of modified and unmodified ZL107 has been compared.The wear resistance of as-cast ZL107 aluminum alloy can be significantly improved after modification.
