Coating of zirconium-based substrates is a promising method to obtain accident-tolerant fuel claddings for light water reactors. In this study, CrSi-based coatings with varying Si content were deposited by multi-arc ion plating, and the effect of Si content on the oxidation behavior of the coatings in air at various temperatures (maximum 1160 °C) was investigated. The solid solution phase, formed by Si in CrSi coating, was seen to improve the oxidation performance of Cr. The nanocomposite structure in CrSiN coating can further improve the oxid...
