一种氧化锆和氧化铝梯度复合涂层及其制备方法
摘要：
本发明涉及一种氧化锆和氧化铝梯度复合涂层及其制备方法，包括多层由不同质量百分比的氧化锆和氧化铝组成的复合层，所述的氧化锆和氧化铝组成的复合层布设在钢基底上。该复合涂层可采用金属有机物化学气相沉积法或反应磁控共溅射方法制备。本发明的氧化锆/氧化铝复合梯度涂层结合了氧化锆和氧化铝的阻氢渗透特性，同时通过调节复合涂层中氧化锆和氧化铝组成比例，可以改变复合涂层的热膨胀系数，改善复合涂层与基体之间的热物理匹配性能，从而改善复合涂层的热循环使用性能。
摘要（英）：

The invention relates to a zirconia and alumina gradient composite coat and a production method thereof. The coat comprises composite layers composed of zirconia and alumina according to different mass percentage ratios, and the composite layers composed of zirconia and alumina are laid on a steel substrate. The composite coat can be produced through a metal organic matter chemical vapor deposition technology or a reactive magnetron co-sputtering technology. The zirconia and alumina gradient composite coat combines the hydrogen resistance and penetration characteristics of zirconia and alumina, and the thermal expansion coefficient of the composite coat can be changed by adjusting the proportions of zirconia and alumina in the composite coat to improve the thermal physical matching performance between the composite coat and the substrate, so the thermal cycle use performance of the composite coat is improved.
