Heat and oxidation resistive high strength material and its production method

摘要

A heat and oxidation resistive high strength material comprising a heat and oxidation resistive coating layer on top of a carbon substrate (1); wherein said heat and oxidation resistive coating layer comprises a SiC type coating (2) fixed on top of said carbon substrate, a ZrO2 type ceramic coating (4) placed on top of said SiC type coating, and an Ir type coating (6) placed on top of said ZrO2 type ceramic coating, is presented. The material is utilized in structural body parts subject to bleaching in high temperature/oxidative atmosphere, the body structure of a space vehicle, a combustor, the combustor for a gas turbine, a turbine blade, and a turbine nozzle. A method for producing this heat and oxidation resistive high strength material is also explained.
