Description

A slip-gelation process was developed for improving the oxidation resistance of matrix graphite of spherical fuel elements. Functionally gradient SiC coating, which is a coating with a compositionally gradient SiC/C layer, was produced by this process by carefully controlling the experimental parameters. The influence of experimental conditions on coating properties was also studied. Oxidation tests showed that samples with dense gradient SiC coating have good oxidation resistance at high temperature in air and good thermal shock resistance. (orig.)
