Abstract
A thermal barrier coating comprises a bond coating 12 made of high temperature corrosion resistance superior to a substrate 11 and a thermal barrier coating 13 made of ZrO2 series ceramics formed on the bond coating. The thermal barrier coating has cracks extending in the direction of the thickness of the barrier coat. Substantially all of the tips of the cracks have a distance between the tips and the boundary at the substrate side.
