摘要
选用AZ91D镁合金作为基体,平均粒径为50μm的SiC颗粒为增强相,采用机械搅拌法制备15vol%SiC_P/AZ91D复合材料。结果表明：通过观察复合材料摩擦磨损曲线,发现SiC颗粒均匀分布,在压缩温度为400℃时复合材料平均摩擦系数最小;比较2 h的AZ91D镁合金基体与复合材料的摩擦磨损曲线,复合材料的耐磨性较合金基体提高了20%,复合材料的平均摩擦系数较合金基体降低了15%。
Through AZ91D alloy was selected as matrix and Si C particle whose average size was 50μm was chosen as reinforcing phase,15vol%SiC_P/AZ91D composites were fabricated by mechanical stirring process.The results show that average friction coefficient of the composites at compression temperature of 400℃is the smallest,owing to the uniform distribution of SiC particles.Compared with AZ91D magnesium alloy matrix for 2 hours,the wear resistance of the composite is increased by 20%and the average friction coefficient of the composites is increased,and the average friction coefficient is decreased by 15%.
