COMPOSITE BOND COAT FOR BLOCKING AND STOPPING CREEP DETERIORATION OF ENVIRONMENTAL BARRIER COATING

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine blade which is subjected to composite bond coat for blocking and stopping the creep deterioration of environmental barrier coating.SOLUTION: The gas turbine blade can contain the bond coat 120 with which the surface of the gas turbine blade is coated. The bond coat can contain silicon and a reactive substance. The reactive substance can react with a thermally grown oxide produced on an adhesive layer to prevent and stop creep. One or more protective layers can be applied on the adhesive layer.
