The Study on Thermal Shock Test of Thermal Barrier Coatings

The requirement of high temperature coatings has been improved with research and production of advanced engine Thermal barrier coatings which has been applied in blades and vanes is a new type coating Thermal shock test has been performed on the TBCs which are prepared by EB PVD The morphology, composition and phase transformation of the TBCs samples is analyzed by SEM, EDXS and XRD
