摘要：

In order to improve the anti-oxidation performance of carbon fiber reinforced silicon carbide matrix (C/SiC) composites, ZrB2 coating was prepared on the surface of C/SiC composites by a two-step technique of pack cementation method. The anti-oxidation properties of coated composites were investigated. The results showed that ZrB2 coating was obtained by the method, which was homogenous and dense. The weight loss percentage of the coated composites was only 1.52 after oxidation in air at 1500 degrees C for 30 min, which exhibited excellent oxidation resistance.
