Abstract: The present disclosure relates to a method for preparing a ceramic thermal barrier coating layer including (a) preparing a first suspension in which first oxide particles for thermal barrier coating are dispersed and a second suspension in which second oxide particles for thermal barrier coating are dispersed, respectively; (b) forming a first coating layer on a base material by suspension plasma spraying (SPS) using the first suspension; (c) forming a buffer layer on the first coating layer by the suspension plasma spraying using a mixed suspension of the first suspension and the second suspension; and (d) forming a second coating layer on the buffer layer by the suspension plasma spraying using the second suspension.
