METHOD FOR COATING MATERIAL OF CERAMIC FOR REDUCING OXIDATION ON THE SURFACE OF GRAPHITE OR C/C COMPOSITE AND THE COATING MATERIAL OF CERAMIC COATED GRAPHITE OR C/C COMPOSITE THEREBY

摘要

The present invention provides a method for coating a ceramic coating material on a base material, comprising: a step of coating the ceramic coating material on a surface of the base material (step 1); a step of generating a crack on the ceramic coating material coated in step 1 (step 2); and a step of coating a gap in the crack with the ceramic coating material (step 3). According to the method for coating a ceramic coating material on a base material in accordance with the present invention, since a gap in the crack is coated with the ceramic coating material after generating a crack on the ceramic coating material, cracks on the ceramic coating material can be inhibited if the base material is used at a high temperature afterward. Accordingly, contact between the base material and air is minimized at a high temperature, thereby greatly improving inhibition of oxidization.
