Abstract

A novel SiC-Si ceramic coating reinforced with well-dispersed SiC nanoribbons was prepared on carbon/carbon (C/C) composites by chemical vapor deposition and pack cementation. The mechanical tests showed that the fracture toughness of the coating and the interfacial bonding strength of the coating-C/C increased by 98% and 99% after incorporating SiC nanoribbons, respectively. The oxidation tests showed that the oxidation of the samples was a continuous weight gain process, and the final weight gain were 61.84g{dot operator}m-2 during thermogravimetric analysis from 300°C to 1500°C and 38.0g{dot operator}m-2 after isothermal oxidation test for 96h, respectively.
