Article having thermal barrier coating

An article comprising:

• a metallic substrate;
• and
• a tri-layer thermal barrier coating deposited on the metallic substrate, the tri-layer thermal barrier coating consisting of an inner ceramic layer, an outermost ceramic layer relative to the metallic substrate, and an intermediate ceramic layer between the inner ceramic layer and the outermost ceramic layer, the outermost ceramic layer including a free, first surface and an opposite, second surface adjacent the intermediate ceramic layer, the inner ceramic layer and the outermost ceramic layer being respectively composed of first and second ceramic materials and the intermediate ceramic layer being composed of a third, different ceramic material selected from the group consisting of hafnia with molybdenum, hafnia with carbon, and combinations thereof, the inner ceramic layer having a first thickness, the outermost ceramic layer having a second thickness, and the intermediate ceramic layer having a third thickness that is greater than the first thickness and the second thickness.
