  • Eutectic ceramic thermal barrier material and preparation method thereof
    Patent number: 11686001
    Abstract: The disclosure provides a eutectic ceramic thermal barrier material and a preparation method thereof, which relates to the field of composite materials. The present disclosure provides a eutectic ceramic thermal barrier material comprising a nickel-based superalloy substrate, an intermediate binding layer and a eutectic ceramic cladding layer stacked sequentially; the intermediate binding layer comprises a NiCoCrAlY binding layer; the eutectic ceramic cladding layer comprises an Al2O3/GdAlO3 binary eutectic ceramic coating or an Al2O3/GdAlO3/ZrO2 ternary eutectic ceramic coating. The eutectic ceramic thermal barrier material provided by the present disclosure has good high temperature resistance, good oxidation resistance and excellent mechanical properties.
