SiC particles were calcined at 1 100℃ in air atmosphere for 6 h to obtain oxidized SiC particles and then immersed in aqueous solution of 5% hydrofluoric acid for 24 h to attain acid-etched SiC particles.Cu coated SiC composite powders were prepared by heterogeneous precipitation coated method and 糖心产精国品免费入口*完整版was used to prepare 糖心产精国品免费入口*完整版s with 35vol% SiC particles.The microstructure and properties of the composites were analyzed.The results show that compared with the composites prepared with original SiC particles,the composites made by high-temperature oxidations and acid-etched SiC particles exhibited different interfacial bonding states with the increase of strength and hardness.The composites made by acid-etched SiC particles had the highest strength and the highest hardness.
