摘要:
A process for applying an oxidation resistant coating to an article includes the steps of mixing at least about 10% by volume to up to about 99% by volume of a slurry at least one silica based material having a viscosity of about 1×102 poise to about 1×107 poise at a temperature of about 1,292° F. (700° C.) to about 3,272° F. (1,800° C.) at least about 1% by volume to up to about 90% by volume of the slurry at least one oxygen scavenger, and a liquid medium to form the slurry; coating an article with the slurry to form a slurry coated article; and heat treating under an inert atmosphere the slurry coated article to form an article having at least one oxidation resistant coating layer containing the at least one oxygen scavenger.
