摘要: A casting system includes a core and a shell positioned relative to the core. A barrier coating is applied on at least one of the core and the shell, and may be applied to both the core and the shell. The barrier coating limits reaction between the casting system and a casting alloy.

摘要: A method of forming a highly densified chemical matrix composite CMC from a preform of a matrix of a non-oxide ceramic and continuous ceramic fibers. An interface coating is added, followed by partially densifying the preform with a resin to increase the density of the preform using a polymer infiltration pyrolysis PIP) process one or more times. A chemical vapor infiltration (CVI) process is used to bring the CMC to a final desired density.

摘要: In a method for coating a molybdenum-based substrate, a molybdenum disilicide layer is formed on the substrate. Aluminum is reacted with hydrochloric gas to produce aluminum chloride. The aluminum chloride is reacted with hydrogen and carbon dioxide to produce alumina. A layer of the alumina is deposited atop the molybdenum disilicide layer.

摘要: A ceramic matrix composite is formed from a non-oxide ceramic and continuous ceramic fibers. The matrix includes a hafnium donor in the matrix in an amount sufficient to harden the composite at elevated temperatures to prevent ablation of the composite. The matrix also includes a boron donor in the matrix in an amount sufficient to lower the glass transition temperature of the composite to flow over cracks formed in the composite. The method to form the matrix is selected from polymer infiltration pyrolysis, chemical vapor infiltration, and sequential polymer infiltration pyrolysis and chemical vapor infiltration.
