AbstractSurface-modified Zr alloy claddings with advanced ceramic coatings are promising materials for accident-tolerant fuel (ATF) systems to meet stringent safety regulations concerning light water reactors. The applications of ceramic coatings are, however, limited as a result of inferior thermal stability when used in conjunction with Zircaloy-4 (Zry-4) substrates. Herein, the thermal stability of sub-stoichiometric zirconium carbide barrier layers as a function of composition was studied. Integrated ceramic coatings comprising ZrC0.55 diffusion barriers and a Cr2AlC top layer were synthesized via a magnetron sputtering method. After rapid thermal annealing, the ZrC0.55 barrier layer having a thickness of 0.5 mu m effectively prevented the inter-diffusion between Cr2AlC and the Zry-4 substrate, thereby ensuring retention of the structural integrity of the integrated ceramic coating system for ATF applications.
