Abstract: The present application provides slot seals for reducing leakages between adjacent components of turbomachinery. The seals may include a metallic shim and a coating overlying the metallic shim. The coating may be a metallic coating, a glass coating, an enamel coating or a ceramic coating. The coating may form an outer surface of the seal for engagement with seal slot surfaces of a seal slot of a turbomachine. The coating may be operable to conform to surface irregularities of the seal slot surfaces and remain coupled to the metallic shim at a predefined operating temperature and a predefined operating pressure to reduce leakage past the seal and thereby between the components. The coating may be configured to flow into depressions formed by the surface irregularities of the seal slot surfaces and remain coupled to the metallic shim at the predefined operating temperature and the predefined operating pressure.

Abstract: The present invention details a process for producing a catalyst powder. The steps of the process include preparing catalyst slurry, drying, pyrolyzing, and calcining the catalyst slurry to obtain a calcined catalyst powder. The catalyst slurry comprises a catalyst, a liquid carrier, a templating agent, and a catalyst substrate. The catalyst slurry is dried to obtain a raw catalyst powder. The raw catalyst powder is heated in a first controlled atmosphere to obtain a pyrolyzed catalyst powder and the pyrolyzed catalyst powder is calcined in a second controlled atmosphere to obtain a calcined catalyst powder. A method of fabricating a catalyst surface and catalytic converter using the prepared catalyst powder is also illustrated.

Abstract: Coating systems and processes by which the coating systems can be deposited to be resistant to contaminants, and particularly resistant to infiltration and damage caused by CMAS. The coating systems include inner and outer ceramic layers. The inner ceramic layer consists essentially of zirconia stabilized by about 6 to about 9 weight percent yttria and optionally contains greater than 0.5 to 10 weight percent hafnium oxide. The outer ceramic layer overlies and contacts the inner ceramic layer to define the outermost surface of the coating system. The outer ceramic layer consists essentially of zirconia stabilized by about 25 to about 75 weight percent yttria, has a thickness that is less than the thickness of the inner ceramic layer and further contains greater than 0.5 to 10 weight percent hafnium oxide and optionally 1 to 10 weight percent tantalum oxide. The outer ceramic layer has a porosity level that is lower than that of the inner ceramic layer.
