Abstract
A method for processing a component is provided and includes masking a first portion of the component with a maskant. The maskant includes a slurry having a plurality of particles in a fluid carrier. The plurality of particles comprises at least one of silicon, carbon, one or more rare earth disilicates, monosilicates or oxides, and combinations thereof. The method includes depositing a silicon-based coating on a second portion of the component via a chemical vapor deposition process and removing the maskant and any overlying silicon-based coating from the first portion of the component.
Claims19
A method for processing a component, comprising:
- masking a first portion of a component with a maskant, wherein the component comprises a ceramic matrix composite material, the maskant including a slurry having a plurality of particles in a fluid carrier, wherein the plurality of particles comprises at least one of silicon, carbon, one or more rare earth disilicates, monosilicates or oxides, or combinations thereof, wherein a second portion of the component is not contacted by the maskant;
- depositing a silicon-based coating via a chemical vapor deposition process on the second portion of the component, wherein the maskant prevents deposition of the silicon-based coating on the first portion of the component;
- and
- removing the maskant and a portion of the silicon-based coating overlaying the maskant from the first portion of the component.
