    摘要: A self-lubricating brush seal assembly, for a power generation system and method of reducing air leakage in a power generation system including a plurality of self-lubricating members is provided. The plurality of self-lubricating members include a plurality of self-lubricating bristles, a plurality of cores sheathed in a self-lubricating braid, a plurality of cores having an outer diameter coated with self-lubricating material and a solid lubricating pack. The lubricating material is selected from graphite, hexagonal-boron nitrite (hBN), molybdenum disulfide (MoS2), tungsten disulfide (WS2), titanium nitride (TiN), titanium aluminum nitride (TiAlN), titanium carbonitride (TiCN), and combinations thereof.

    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.

    摘要: A process of applying a porous metallic structure and a cold-sprayed article are disclosed. The process includes cold spraying a solid feedstock and a low-melt material onto an article and removing at least a portion of the low-melt materials or applying a porous metallic structure includes cold spraying onto an article with two converging-diverging nozzles. The cold-sprayed article includes a porous metallic structure having a portion formed from cold spraying a solid feedstock. The portion includes the phases and microstructure of the solid feedstock.
