Abstract (en)

A thermal insulating ceramic layer for use on metal alloy components exposed to hostile thermal and chemical environment, such as a gas turbine. The thermal barrier coating may include cracks made by a series of steps, including subjecting at least a portion of the thermal barrier coating to a shockwave such that microcracks are formed in the thermal barrier coating without also substantially deforming the substrate.
