自从McrAlY涂层成功的用于收音机涡轮发动机部件的保护层，这项技术迅速地推广到陆地高温部件的应用中。服务环境也得到迅速推广。但是目前，这类涂层的抗高温腐蚀性能应用条件仍处在争论中。只有特定的应用环境确定后，才能决定使用特定涂层。这类涂层除了应用于表层，还应用于热障涂层的边界层。 Since the success of the McrAlY coating for radio turbine engine components of the protective layer, the technology quickly extended to the application of high temperature components on land. The service environment has also been rapidly promoted. However, at present, the application conditions of the high temperature corrosion resistance of such coatings are still under debate. Only after a certain application environment has been determined, can it be decided to use a specific coating. In addition to this type of coating applied to the surface, but also applied to the thermal barrier coating boundary layer.
