Pyrolytic carbon (PyC) coating is deposited on IG-110 nuclear graphite to protect it against the impregnation of molten Flinak salt. Raman spectroscopy, near-edge X-ray absorption fine structure (NEXAFS) spectroscopy, and X-ray photoelectron spectroscopy (XPS) are used to investigate the effect of defects induced by 12C+ ion irradiation on the fluorination of PyC coating in Flinak salt. Results show evidence for the formation of C[BOND]F bond. And the defects induced by ion irradiation facilitate the fluorination of PyC coating in Flinak salt.
