The potential benefits of a thermal barrier coating on the heated side of diesel or turbine components are well documented, and this as well as other applications of ceramics in heat engines are being actively pursued. The ceramic coatings used in heat engines must be able to withstand severe thermal stress. The microstructure and properties of several sprayed coatings are described, including flame‐sprayed alumina coatings, plasma‐sprayed alumina coatings, and plasma‐sprayed zirconia coatings. The results show that the modulus ( E ) of the coatings depends mainly on porosity and phase composition, and nonlinear stress‐strain behavior is caused by the laminar grain structure of the coatings. The fracture strain of a coating is a major factor in the thermal shock resistance of that coating.
