Research abstract
SIC COATINGS CAN PROTECT CARBON COMPOSITES FROM OXIDATION UP TO ABOUT 3000F. ZRO2 AND HFO2 HAVE BEEN APPLIED AS OVERCOATINGS TO EXTEND OXIDATION PROTECTION TO 3500F, BUT THESE LAYERS TEND TO SPALL. WE PROPOSE HERE AN INNOVATIVE METHOD OF GRADING THE COATING FROM PURE SIC AT THE C/C INSIDE SURFACE TO PURE HF (OR ZR) OXIDE AT THE OUTSIDE SURFACE. THIS IS THE MOST EFFECTIVE WAY TO ELIMINATE THERMAL STRESS CONCENTRATION AND OVERCOME THE CRACKING AND SPALLING PROBLEM.
