一种复合阻氢涂层及其制备方法
摘要：
本发明公开了属于金属材料技术领域的一种复合阻氢涂层及其制备方法。所述复合阻氢涂层包括依次布设的不锈钢基体、金属过渡层和金属氧化物涂层，复合阻氢涂层的外层分别为不锈钢基体和金属氧化物涂层。不锈钢基体为马氏体不锈钢或奥氏体不锈钢，金属过渡层为金属Al过渡层，金属氧化物涂层为Al2O3涂层。所述复合阻氢涂层由气相沉积法制备，通过重复沉积金属过渡层和其氧化物涂层，获得总厚度为0.1-5μm厚的复合阻氢涂层。所述阻氢涂层与基体结合强度高、制备工艺简单且成本低廉，在600℃工作温度下，阻氢性能可提高500倍以上。
摘要（英）：

The invention discloses a composite hydrogen retention coating and a preparation method thereof, and belongs to the technical field of metal materials. The composite hydrogen retention coating includes a stainless steel substrate, a metal transition layer and a metal oxide coating which are arranged in sequence; the outer layer of the composite hydrogen retention coating is provided with the stainless steel substrate and the metal oxide coating; and the stainless steel substrate is made of martensitic stainless steel or austenitic stainless steel, the metal transition layer is a metal Al transition layer, and the metal oxide coating is a Al2O3 coating. The composite hydrogen retention coating is prepared by a vapor deposition method. By repeatedly depositing the metal transition layer andthe oxide coating, the composite hydrogen retention coating with the total thickness being 0.1-5 microns is obtained. The hydrogen retention coating and substrate bonding strength is high, the preparation process is simple, the cost is low, and the hydrogen retention performance can be improved by more than 500 times at the working temperature being 600 DEG C.
