摘　　要：采用不同的浇注温度制备了ADC12-0.15%Ti-0.1%Sr铝基汽车动力转向器壳体,进行了耐磨损性能和冲击性能研究。结果表明,随浇注温度在620~720℃变化,转向器壳体的耐磨损性能和冲击性能均先提高后下降。汽车动力转向器壳体的最佳浇注温度工艺参数为680~700℃。ADC12-0.15%Ti-0.1%Sr aluminum-based automobile power steering gearbox specimens were produced with various pouring temperatures, the wear resistance test and impact test were conducted. The results show that with pouring temperatures from 620℃ to 720 ℃, the wear resistance and impact property of the specimen first increases and then decreases. The best pouring temperatures is 680~700 ℃.
