Abstract
The present disclosure includes carbon-carbon composite articles having multiphase glass oxidation protection coatings for limiting thermal and/or catalytic oxidation reactions and methods for applying multiphase glass oxidation protection coatings to carbon-carbon composite articles.
Claims7
An article comprising:
- a carbon-carbon composite structure;
- and
- a multiphase oxidation protection composition including a first glass phase and a second glass phase on an outer surface of the carbon-carbon composite structure,
- wherein the first glass phase comprises a phosphate glass composition having a first transition temperature,
- wherein the second glass phase comprises a second transition temperature higher than the first transition temperature, and
- wherein the second transition temperature is at least 100° C. higher than the first transition temperature.
