摘要：

Carbon-carbon composites were coated with Calcium Magnesium Zirconium Phosphate (CMZP) and Mg-doped Al2TiO5 sol-gels in order to form an oxygen barrier at temperatures above similar to 650 degrees C. The coatings were applied using a dipping technique and controlled drying procedures. It was determined that 10 coats of CMZP sol-gel fired every other coat created crack free coatings and oxidation protection. Mg-doped AlTi2O5 coatings produced were unsuccessful as oxidation barriers. (C) 1999 Kluwer Academic Publishers.
