摘要	The great advantages of component designability, operation convenience, and cost reduction make the slurrysintering method promising for preparing oxidation resistant coatings. However, the porous structure caused by the volatilization of liquid in the slurry and shrinkage of particles in the pressureless sintering limits its practical and wide application. Herein, a dense ZrB2-SiC coating with improved oxidation resistance was fabricated via a slurry -sintering method on C/SiC composites by introducing kyanite into the slurry. The selfdensification of the coating is achieved due to the volume expansion of 26.1 % related to the irreversible thermal transformation from kyanite to mullite during sintering. The resultant dense coating with a thickness of 150 mu m shows the good interfacial bonding strength of 19.2 MPa and the low weight changes of 1.7 %, -0.6 %, and -1.7 % at 800 degrees C, 1000 degrees C, and 1200 degrees C for 40-h oxidation, respectively.
