Abstract: To enhance the anti-temperature oxidation performance of Zr alloys in the nuclear industry, Cr coatings with a thickness of 10.5 μm were prepared on Zr-4 alloys by DC magnetron sputtering. The bonding strength between the Cr coating and the Zr-4 alloy matrix was tested using scratch experiments. The oxidation behaviour of the Cr coatings in air environment at 400 ℃, 600 ℃ and 800 ℃ was investigated by oxidation weight gain experiments. The surface and interface of the Cr coatings before and after oxidation were characterized by SEM/EDS. The results show that the bonding force between the Cr coating and the substrate prepared by magnetron sputtering exceeds 87 N. The surface of the coating is dense and presents a worm-like shape. The Cr coating shows a preferred orientation at (110). The results of weight gain show that the rate of oxidation weight gain increased with oxidation temperature increased. According to the analysis of oxidation kinetics, the weight gain of Cr coating follows a parabolic relationship with time. Compared with the oxidation weight gain of Zr-4 alloy, it was found that the diffusion rate of O atoms was slower when oxidized at 400 ℃ for 120 h. The oxidation kinetics constant kp of Cr coating is 7.67×10-9(mg/cm2)2/s, which is about 3/4 of that of Zr-4 alloy. After 75 h of oxidation at 600 ℃, the oxidation kinetics constant kp of the Cr coating is 2.39×10-7(mg/cm2)2/s, which approximately 1/4 of that of Zr-4 alloy, protecting the Zr-4 substrate from rapid oxidation. After 12 h of oxidation at 800 ℃, the oxidation kinetics constant kp of the Cr coating is 9.75×10-4 (mg/cm2)2/s. The Cr coating peeled off and the anti-oxidation ability of the coating failed, mainly due to the joint oxidation of the Cr coating and Zr-4 substrate. The output of this work may provide theoretical support and practical significance for the service of Cr coatings under normal operating conditions.
