Self-densification behavior, interfacial bonding and cyclic ablation resistance of HfSi2-ZrSi2 modified SiC/ZrB2-SiC/SiC coating for Cf/SiC composite
Source abstract
Abstract
A slurry method has good prospects in preparing coatings, yet great challenge to apply dense coatings due to the volatilization of slurry and the inert and pressureless sintering. Here we develop a HfSi 2-ZrSi 2 modified SiC/ZrB 2 -SiC/SiC triple-layer coating by an improved slurry method combined with CVD on C f/SiC composites. The ZrSi 2 and HfSi 2 are preferentially oxidized in a novel oxygen-containing sintering process so that their generated SiO 2 glass can heal defects to achieve self-densification of the coating. Resultantly, the coating presents outstanding interfacial bonding strength of 14.7 MPa and excellent cyclic ablation resistance at 1800 °C for 600 s
