英文摘要SiC coating on graphite flake (G(f)) was prepared by SiO2 sol-gel method combining with in-situ reaction. Then, the SiC coated graphite flakes reinforced 6063A1 (SiC@G(f)/6063Al) composites were fabricated by vacuum hot pressing method. The results demonstrated that the SiC coating with a thickness of about 15 nm on the G(f) could effectively improve the wettability, reduce the interface thermal resistance, and enhance the bonding between G(f) and Al matrix. As a result, the bending strength as well as the thermal conductivity of the SiC@G(f)/6063Al composites was much higher than those of the G(f)/6063Al composites. Especially, the 50 vol% SiC@G(f)/6063Al had the highest bending strength of 52.5 MPa, and the thermal conductivity of the 70 vol% SiC@G(f)/6063Al reached the highest value of 731.4 W m(-1) K-1.
