Abstract
PRESENT STATE OF THE ART THERMAL BARRIER COATINGS DEPOSITED BY ARC-PLASMA SPRAYING FAIL JUST ABOVE THE CERAMIC/BONDCOAT INTERFACE DUE TO ACCUMULATED STRESSES WHICH RISE DURING THERMAL CYCLING. THE PROPOSED PROJECT EXPLORES THE INCLUSION OF STRENGTHENING SIC WHISKERS OR PLATELETS TO COMBAT THESE STRESSES. WHEREAS PREVIOUS ATTEMPTS HAVE CAUSED DISASSOCIATION OF THE SIC, WE PROPOSE A STAGGERED INJECTION ARRANGEMENT TO AVOID SUCH PENALTY. THE CONCEPT WILL BE VERIFIED BY FULL CHARACTERIZATION OF THE COATINGS AND BY THERMAL CYCLE TESTS USING ALUMINUM SUBSTRATE AND AN IN-HOUSE BURNER RIG.
