Abstract
A coating system having a low thermal conductivity, and a method by which the low thermal conductivity of the coating system is maintained through the development of cracks within a thermal-insulating layer of the coating system. The thermal-insulating layer is a mixture of two or more materials with different coefficients of thermal expansion (CTE). The materials of the thermal-insulating layer are selected and combined so that a low thermal conductivity is maintained for the coating system as the result of cracks developing and propagating from interfaces between the materials when the coating system is subjected to heating and cooling cycles.
