为了在锆合金管材表面制备一种抗高温氧化性能优良的复合涂层,采用多弧离子镀技术,在锆管表面先用纯铬靶沉积Cr过渡层,再用TiAlSi靶通入氮气反应沉积TiAlSiN表面层,制得了Cr/TiAlSiN复合涂层。对锆合金单一Cr涂层和Cr/TiAlSiN复合涂层试样进行了淬火对比试验;对锆合金基材和Cr/TiAlSiN复合涂层试样进行了高温水蒸气氧化对比试验。肉眼观察1 200℃淬火前后宏观形貌,用SEM观察涂层1 200℃水蒸气氧化前后微观形貌,热重试验法测试样品在水蒸气氧化过程中的重量变化、氧化反应速率。结果表明:复合涂层在1 200℃淬火条件下未见剥落和开裂现象,而单一Cr涂层淬火后出现局部剥落;锆管基材经水蒸气氧化后表...

A composite coating with high oxidation resistance was prepared on the surface of zirconium tube. The multi-arc ion plating technology was used to deposit the Cr transition layer on the surface of zirconium tube with pure chromium target,and then TiAlSiN surface layer was deposited with TiAlSi target through nitrogen reaction to form the Cr /TiAlSiN composite coating. The quenching comparative experiments of single Cr coating and Cr /TiAlSiN composite coating samples of zirconium alloy were carried out,and the high temperature steam oxidation c...
