摘要	Cr0.5Al0.5Nx (x = 0.33, 0.81, 1.23) coatings were deposited on Zry-4 alloy using magnetron reaction sputtering technique to investigate their application as accident-tolerant fuel materials. The effects of nitrogen (N) content on the phase composition and high-temperature steam oxidation resistance of the coatings were systematically investigated. With the increasing N content, the phase composition of the coatings is mainly transformed from Cr(Al) to the cubic-CrAlN phase, which may be due to the formation of a greater number of CrN bonds and AlN bonds. The high-N content of the Cr0.5Al0.5Nx coating can significantly enhance the high-temperature steam oxidation resistance of zirconium alloy. Compared to the bare Zr alloy, the weight gain oxidation of the Cr0.5Al0.5N1.23 coating is reduced by 45 % after oxidation at 1200 degrees C for 1 h. The oxide layer thickness of the bare Zry-4 alloy is as high as 350 mu m, while the oxide layer thickness of the Cr0.5Al0.5N1.23 coating is only about 12 mu m. The complex oxide layer structure and an internal continuous Al2O3 layer are formed, effectively preventing the inward diffusion of O2-. In addition, with the increase of N content in the coatings, the degree of interdiffusion between the coating and the substrate is weakened. The formation of alpha-Zr(N) layer in the Cr0.5Al0.5N1.23 coating significantly inhibits the interdiffusion between the coating and the substrate.
