Abstract

High temperature thermal shock causes the breakdown of Thermal Barrier Coating (TBC) systems. This paper focusing attention on the Zirconate TBC coating to study the thermo mechanical behavior such as wear and thermal shock test has been conducted inter metallic bond coat and Zirconate TBC to know the wear and thermal characteristics, and wear behavior has been studied on intermetallic bond coat using dry abrasion test and thermal characteristics studied on Zirconate TBC systems using thermal shock resistance test and finally the coatings characteristics before and after thermal cycling were evaluated.
