Method of manufacturing fiber reinforced barrier coating
A method of manufacturing a fiber reinforced coating. The method includes providing a substrate and plasma spraying a ceramic matrix having fibers encapsulated in a precursor material onto the substrate.
1. A method of manufacturing a fiber reinforced coating, the method comprising:
providing a substrate;
encapsulating fibers in a precursor material;
co-spraying the encapsulated fibers with a ceramic matrix material other than the precursor material onto the substrate, wherein the co-spraying is plasma spraying; and
after the plasma spraying, heat treating the encapsulated fibers and ceramic matrix material, the heat treating step comprises at least one of pyrolyzing the precursor material or calcinating the precursor material, and the heat treating step reduces at least a number or size of voids in the ceramic matrix material, wherein the pyrolyzing or calcinating occur at approximately 700° C. (1290° F.).
