EROSION AND CORROSION RESISTANT COATINGS FOR EXHAUST GAS RECIRCULATION BASED GAS TURBINES |
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. |
