摘要： A ceramic component is generally provided that includes a silicon-based layer comprising a silicon-containing material (e.g., a silicon metal and/or a silicide) and about 0.001% to about 85% of an In-containing compound. For example, the silicon-based layer can be a bond coating directly on the surface of the substrate. Alternatively or additionally, the silicon-based layer can be an outer layer defining a surface of the substrate, with an environmental barrier coating on the surface of the substrate. Gas turbine engines are also generally provided that include such a ceramic component.

摘要： A hot gas path component of an industrial machine includes a cooling pathway. The component includes a body including an outer surface; a thermal barrier coating (TBC) over the outer surface, the TBC exposed to a working fluid having a high temperature; and an internal cooling circuit in the body carrying a cooling medium. A cooling pathway is in the body and in fluid communication with the internal cooling circuit. The cooling pathway includes a terminating end in the body and a length extending along and spaced internally from the outer surface by a first spacing. In response to a spall in the TBC occurring at a location over the cooling pathway and the high temperature reaching or exceeding a predetermined temperature of the body, the cooling pathway opens at the location through the first spacing to allow a flow of the cooling medium therethrough.

摘要： Methods for fabricating protective coating systems for gas turbine engine applications are provided. An exemplary method of applying a protective coating to a substrate includes the steps of providing a substrate formed of a ceramic matrix composite material, forming a first coating layer directly on to the substrate and comprising an oxygen barrier material, a compliance material, or a bonding material and forming a second coating layer directly on to the first coating layer and comprising a thermal barrier material. The method optionally includes forming a third coating layer partially directly on to the second coating layer and partially within at least some of the plurality of pores of the second coating layer.

摘要： An indentation tester and indentation method for testing a sample heated at a temperature range from above 800° C. to 1200° C., and above, is disclosed. The indentation tester includes a stage having a metallic cylindrical base that houses an inner cylindrical base made of a temperature resistant material sufficient to maintain shape over the range of the heating temperature. A removable crown fastens to the cylindrical base and includes a ring that holds an axisymmetric pipe made of a temperature resistant material sufficient to maintain shape over the range of heated temperature. A nut is turned to tighten the pipe which secures the sample and guides an indenter to penetrate the sample. The indenter includes a rod made of temperature resistant material and a indenter tip.
