The compound SiC slide member, being sealing ring for mechanical seal and the compound SiC slide member where the spherical carbon distributes during

摘要

PROBLEM TO BE SOLVED: To provide a sliding member hardly causing the dropping-out of an antifriction with high denseness and having self-lubricating property as graphite. SOLUTION: This composite SiC sliding member comprises spherical carbons 1 dispersed in a dense SiC texture 3. An intermediate layer 2 is formed on the periphery of each spherical carbon 1, and the intermediate layer 2 is a graphitized layer.
