Title:
METHOD FOR MANUFACTURING CERAMIC THERMAL BARRIER COATING LAYER HAVING EXCELLENT ADHESIVE STRENGTH AND HEAT DURABILITY
Document Type and Number:
WIPO Patent Application WO/2019/107895
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a ceramic thermal barrier coating layer, the method comprising the steps of: (a) preparing a first suspension in which first oxide particles for a thermal barrier coating are dispersed and a second suspension in which second oxide particles for the 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 suspension plasma spraying using a suspension obtained by mixing the first suspension with the second suspension; and (d) forming a second coating layer on the buffer layer by suspension plasma spraying using the second suspension.
