Abstract
There is provided an improved coated composite article and an improved process for making the article. A cloth-like flexible preform is brazed to a metallic substrate to make the article. The article is then subjected to a uniform high pressure and temperature for sufficient time to remove porosity in the coating. The result is a fully dense coating, which is metallurgically bonded to the substrate without any porosity, which has improved physical properties, and which is capable of being polished to a surface finish of at least 4 RMS.
