摘　　要：探究Al含量对Cr-Al涂层的抗高温氧化性能影响,得到最适合Cr-Al涂层的Al元素量,通过磁控溅射沉积技术在锆合金表面制备了4～6μm的铬铝涂层。研究了Al、Cr_(0.5)Al_(0.5)、Cr_(0.9)Al_(0.1)、Cr四种涂层在600℃静态空气环境中氧化270 min,测试涂层对锆合金抗高温氧化的防护作用。结果表明:铬铝涂层对锆合金具有较好的抗高温氧化性能,其中Cr涂层较其他三种抗高温氧化性能最佳。The effect of Al content on the high temperature oxidation resistance of Cr-Al coating is investigated. The amount of Al element which is most suitable for Cr-Al coating is obtained. 4~6 μm chromium aluminum is prepared on the surface of zirconium alloy by magnetron sputtering deposition technique. Al,Cr0.5Al0.5,Cr0.9Al 0.1,Cr coatings are oxidized in a static air environment at 600 ℃ for 270 min to test the protective effect of the coating on high temperature oxidation resistance of zirconium alloy. The results show that the chrome-aluminum coating has good high-temperature oxidation resistance to zirconium alloy, and the Cr coating has the best resistance to high temperature oxidation compared to the other three coatings.
