Abstract: This disclosure provides a method of pressure sintering an environmental barrier coating on a surface of a ceramic substrate to form an article. The method includes the steps of etching the surface of the ceramic substrate to texture the surface, disposing an environmental barrier coating on the etched surface of the ceramic substrate wherein the environmental barrier coating includes a rare earth silicate, and pressure sintering the environmental barrier coating on the etched surface of the ceramic substrate in an inert or nitrogen atmosphere at a pressure of greater than atmospheric pressure such that at least a portion of the environmental barrier coating is disposed in the texture of the surface of the ceramic substrate thereby forming the article.

The assembly includes a second tube defining a second smooth, planar surface at an end of the second tube. The assembly includes a force mechanism configured to apply a force to at least one of the first tube or the second tube to maintain contact between the first surface and the second surface. The first surface and the second surface are configured to interface to form a substantially hermetic seal when the assembly is cycled through a temperature cycle. The force is substantially normal to the first and second surfaces.

Abstract: An example method for forming a high temperature coating includes depositing a carbon layer on to a surface of a composite article using chemical vapor deposition. The composite substrate includes a composite substrate including a carbon matrix. The surface of the composite article includes one or more surface voids. The method further includes applying a metal slurry to the surface of the composite article following the deposition of the carbon layer and reacting a metal of the metal slurry with carbon of the carbon layer to form an antioxidant layer of a metal carbide on the composite article.
