C的加入量为6%时

复合材料性能达到最佳

抗拉强度提高了17%

硬度提高了34%

磨损率降低了34%。

C/Al matrix composites were prepare at 800 ℃ by mechanical stirring with Ar protection and A356 aluminum alloys as matrix. The effects of B

C addition on properties of composites were analyzed.The properties were characterized through the mechanical property experiments

microstructure observation

friction and wear performance tests. The results indicate that the performance of compositesis reaches the satisfied effect with B

C content of 6%

where the tensile strength and hardness are increased by 17%

34% and wear rate is decreased by 34%.
