Abstract
The disclosure is concerned with a thermal land machine which comprises a heat resistant wall for confining a chamber; a heat resistant composite structure disposed in the chamber and in contact with a hot flowing gas; and an apparatus for introducing the hot gas toward the surface of the composite structure. The composite structure including a heat resistant substrate and a continuous refractory coating formed on the substrate and made of a ceramic material. The refractory coating includes at least two layers in a laminated structure each having fine cracks substantially extended in the direction of the thickness of each of the layers and filled with a refractory material in such a manner that the filled cracks in one layer are disconnected with the filled cracks in the adjacent layer. Therefore, the hot gas cannot permeate into the surface of the substrate.
