AlSiC复合材料拥有比铝合金更高的比强度和比模量、耐高温、耐磨损、高导热率、可调节热系数等优点,在航空航天、汽车、电子、军工等领域有重要应用。由于 SiC 增强相的高硬度和铝基体的高塑性,使得该类材料在切削加工、磨削加工及非传统加工的方面可加工性较差。为了获得高的表面质量和精度,磨削加工是必不可少的一种加工方式,文章针对 AlSiC复合材料的磨削加工研究现状进行综述,重点对磨削加工中材料表面完整性、磨削砂轮的磨损形式和磨削加工工艺等方面进行总结和分析。

In comparison with aluminum alloy,AlSiC composite materials have higher specific strength,specific modulus,high-temperature resistance,wear resistance,high thermal conductivity and tunable thermal expansion coefficient,and were widely used in the aerospace,automotive,electronics and military fields etc.Due to the higher hardness of SiC reinforcement and the higher ductility of aluminum matrix phase,machining of AlSiC composite materials was a tough work.In this paper,the advance of research on grinding of AlSiC composites materials was reviewed.The surface integrity of the ground AlSiC composite materials,the wear of grinding wheels and the grinding process were summarized and analyzed.
