| 英文摘要 | Accident tolerant fuel claddings are extremely urgent to increase the safety margin of light water reactors. In this work, Cr-Al-Si ternary alloy coatings were proposed to increase high-temperature oxidation resistance of zirconium claddings. Cr62.8Al27.9Si9.3 coatings were deposited on Zr coupons by magnetron sputtering, followed by evaluation of their oxidation resistance and adhesion strength under high-temperature steam. No oxidation of the Zr coupons underneath the coatings occurred in the 1000 degrees C steam for 15 min. In the 1200 degrees C steam for 30 min, both the weight gain and the thickness of the alpha-Zr(O) layer decreased 40% and 50%, related to those of the uncoated coupons, respectively. Moreover, the adhesion of coating and substrate was improved after the high-temperature oxidation, with the adhesion strength of the oxidized coating - Zr substrate more than similar to 50 N. It was further observed that the Al and Si atoms preferentially diffused outwards the surface to form a layer of oxides, and the atoms diffused towards the Zr substrate to form a mixed interlayer. The outside barrier layer and the inter-diffused layer could contribute to the enhanced oxidation resistance and the adhension of the coated Zr coupons, which would be highly desirable for the zirconium claddings. |
