Abstract
The present disclosure provides a method for coating a composite structure, comprising forming a first slurry by combining a first pre-slurry composition comprising a first phosphate glass composition, with a primary flow modifier and a first carrier fluid, wherein the primary flow modifier comprises at least one of cellulose or calcium silicate; applying the first slurry on a surface of the composite structure to form a base layer; and heating the composite structure to a temperature sufficient to adhere the base layer to the composite structure.
Claims5
An article, comprising:
- a carbon-carbon composite structure;
- and
- an oxidation protection system including a base layer disposed on an outer surface of the carbon-carbon structure, wherein the base layer comprises a first pre-slurry composition having a first phosphate glass composition, a primary flow modifier, and a secondary flow modifier, wherein the primary flow modifier comprises at least one of cellulose or calcium silicate, and wherein the secondary flow modifier comprises at least one of poly(vinyl alcohol) or a salt of poly(acrylic acid).
