摘要：
It is disclosed a method of depositing a seal coating and a seal system comprising at least two layers on the surface of an article. The upper or surface layer has a higher chromium activity than a bottom layer, to reduce a diffusion of cobalt and the formation of cobalt oxide is reduced. The coating of invention may be heat-treated to reduce or optimize the formation of cobalt oxide to sustain the wear property.
