摘　　要：研究了SiC增强铝基复合材料的半固态法制备 ,分析了SiC颗粒与基体金属之间的润湿性 ,提出了解决SiC颗粒与基体金属之间润湿的措施。结果表明 :将SiC颗粒进行高温处理 ,在其表面涂覆K2 ZrF6,在 2A11合金熔体中添Mg元素 ,可改变SiC与铝基体的浸润性。The 2A11 matrix composite reinforced by SiC was studied, which was fabricated by semi solid casting. The influence factor of wetting between SiC and matrix metal was analyzed, and the way was supplied to solve this problem. The results show that the wettability can be improved by treating SiC in high temperature, coating K 2ZrF 6 on it, and adding Mg in 2A11 alloy.
