摘要：

SiC coating is produced on a nuclear graphite (NG) substrate using chemical vapor deposition at 1150 degrees C to protect it from molten salt diffusion. Infiltration studies, performed in molten FLiNaK salt under an argon atmosphere at 5 atm, show that uncoated NG exhibits significantly higher weight gain than SiC-coated NG. The continuous and compact SiC coating exhibits excellent infiltration resistance in liquid fluoride salt as confirmed by synchrotron radiation X-ray microbeam fluorescence. (C) 2014 Elsevier B.V.
