    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 method, in certain embodiments, includes providing a metal alloy, annealing the metal alloy, and contacting the metal alloy with vapors of selenium, or sulfur, or a combination thereof. The metal alloy having a uniform first bulk composition and a first surface composition on annealing provides an annealed metal alloy having a non uniform second bulk composition and a second surface composition which on being contacted vapors of selenium, or sulfur, or a combination thereof, produces a selenized or a sulfurized metal alloy. Further the metal alloy may have a layer formed in situ from a low melting point metal within the alloy via diffusion rather than sequential deposition and co-evaporation.

    摘要： An electrolyte separator structure is provided. The electrolyte separator structure comprises a graded integral structure, wherein the structure comprises an ion-conducting first ceramic at a first end and an electrically insulating second ceramic at a second end, wherein the difference in the coefficient of thermal expansion of the ion-conducting first ceramic and the electrically insulating second ceramic is less than or equal to about 5 parts per million per degrees Centigrade, and wherein at least one of the first ceramic or the second ceramic comprises a strengthening agent. Method of making the ion-separator structure is provided. Electrochemical cells comprising the ion-separator structure and method of making the electrochemical cell using the ion-separator structure are also provided.
