“…Therefore, research efforts are underway to develop surface coatings using metals or their compounds such as Ti, Cr, ZrC, CrN, TiN, and ZrN. [11][12][13][14][15] However, delamination of these coatings has been reported after neutron irradiation, primarily on account of the differences in the volume expansion induced by neutron irradiation between the metal coatings and SiC. Since the optimal approach comprises applying coatings to ceramic substrates with comparable irradiation behaviors, some research is being carried out to develop corrosion-resistant ceramic coatings, such as dense SiC deposited by chemical vapor deposition (CVD) and oxide ceramics of approximately 15 µm thick.…”
