Method and apparatus for testing performance of thermal barrier coating layer

Abstract

A method and an apparatus for testing thermal performance of a coating layer are provided. The method for testing thermal performance of a coating layer involves obtaining a first thermal gradient by exposing one side of a metal base test piece to heat and exposing another side of the metal base test piece to a cooling air; obtaining a second thermal gradient by exposing a coating layer side of a coating layer test piece to heat and exposing an opposite side to a cooling air; calculating an exterior temperature Tf of a coating layer of the coating layer test piece and a temperature Te of a boundary side of the coating layer using the first thermal gradient; and calculating a temperature difference TΔ between the exterior temperature Tf of the coating layer and the temperature Te of the boundary side of the coating layer.
