Abstract
A slip-gelation process was developed for improving the oxidation resi stance of matrix graphite of spherical fuel elements. Functionally gra dient 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 sampl es with dense gradient SIC coating have good oxidation resistance at h igh temperature in air and good thermal shock resistance. (C) 1998 Els evier Science B.V.
