    摘要: A coated article and a coating application process are disclosed. The coated article includes a metallic surface, a first layer positioned proximal to the metallic surface, the first layer having a first ductility, and a second layer positioned distal from the metallic surface, the second layer having a second ductility. The first ductility is at least about 20% greater than the second ductility. The process includes providing an article, the article comprising a metallic surface, applying a first layer proximal to the metallic surface, the first layer having a first ductility, and applying a second layer distal from the metallic surface, the second layer having a second ductility.

    摘要: A compressor blade for use in a compressor section of a gas turbine engine, comprising: a martensitic stainless steel compressor blade and an abrasive coating having an anodic component. The compressor blade has a blade portion, a dovetail portion and a platform portion intermediate the blade portion and the dovetail portion, the blade portion terminating in a tip opposite the dovetail portion. A cobalt-based coating overlies at least the blade portion of the compressor blade. The cobalt-based coating comprises a cobalt based material that includes precipitates of tungsten carbide that provide erosion resistance and particles of a sacrificial metal-based material distributed through the cobalt-based coating that provide galvanic corrosion resistance to the system.
