Abstract: A method of preparing a ceramic matrix composite (CMC) article is disclosed. The method includes depositing a first layer of a coating composition directly onto a surface of a silicon carbide fiber-reinforced silicon carbide matrix (SiC/SiC) composite substrate, with the coating composition comprising a rare earth silicate and a sintering aid. The method also includes heating the first layer to sinter the coating composition to form an environmental barrier coating (EBC) adjacent the SiC/SiC composite and a transition layer integrally bonded to and between the substrate and the EBC. CMC articles prepared according to the method, including coated turbomachine components, are also disclosed.

Abstract: A method of applying a protective coating to a substrate includes the steps of: providing a turbine engine component substrate formed of a ceramic matrix composite material, forming an environmental barrier coating layer including a rare earth disilicate material directly on the substrate, treating an outer surface of the environmental barrier coating layer to form a thermal barrier coating layer including a porous rare earth monociliate material directly on the environmental barrier coating layer. The step of treating the outer surface is performed using a thermal process consisting of the application of heat or a chemical-thermal process consisting of the application of heat and a chemical. The method further includes infiltrating at least a portion of the pores with a metal solution or suspension.

Abstract: A method for manufacturing an electromagnetic coil with an intentionally engineered heat flow path is provided. The method includes defining at least one preferential heat flow path for heat to flow for the electromagnetic coil. A coil cartridge in which to encase the electromagnetic coil is designed by selecting dimensions of different portions of the insulating coil cartridge that will result in the at least one preferential heat flow path. The electromagnetic coil is then encased in coil cartridge material to produce an encased electromagnetic coil.
