Abstract
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.
Claims20
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 and a ceramic matrix material onto the substrate using plasma spraying, the ceramic matrix material made of a different material than the precursor material;
- and
- heat treating the encapsulated fibers and the ceramic matrix material after the co-spraying step, the heat treating step comprises at least one of pyrolyzing the precursor material or calcinating the precursor material at approximately 700° C. (1290° F.), and the heat treating step reduces at least a number or size of voids in the ceramic matrix material.
