    摘要: A method is provided for high velocity air plasma spraying (APS) application of a protective coating system, such as a bond coat with or without an overlying ceramic thermal barrier coat, to a superalloy metal substrate. Application of MCrAlY alloy bond particles (where M is at least one of iron, cobalt, or nickel) onto the metal substrate is maintained at a particle velocity of at least 400 meters per second (m/s), for example within a range of 400 m/s to 700 m/s. The resulting bond coat on the metal substrate has a surface roughness of about 300 to about 500 μinch Ra, and a density of at least 90% of theoretical density. The protective coating may include a ceramic thermal barrier coat applied over the bond coat by any suitable process.

    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.
