【Abstract】 Carbon/BN composites were firstly formed by hot pressing, then were treated with impregnation,solidification and carbonization processes in turn. Properties of the sealing composite were investigated. Test results show that the carbon/BN composites are kinds of mechanical sealing materials with anti oxidation function at high temperature and excellent self lubricity更多还原
