Abstract
A method for preparing a thermal barrier coating (TBC) material includes: spraying a metal mixture onto a surface of an alloy using supersonic flame spraying or explosive spraying to form a bottom layer; spraying an yttria-stabilized zirconia (YSZ) precursor sol onto the bottom layer using liquid plasma spraying to form an intermediate layer; and spraying a ceramic composite including SiOand La—Ce—Zr—O using plasma spraying or explosive spraying to form a surface layer.
