    Abstract: 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.

    Abstract: A gas sensor is disclosed. The gas sensor includes a gas sensing layer including doped oxygen deficient tungsten oxide and a dopant selected from the group consisting of Re, Ni, Cr, V, W, and a combination thereof, at least one electrode positioned within a layer of titanium, and a response modification layer. The at least one electrode is in communication with the gas sensing layer and the gas sensing layer is capable of detecting at least one gas selected from the group consisting of NO, NO2, SOx O2, H2O, and NH3. A method of fabricating the gas sensor is also disclosed.
