Project Overview
Conventional Thermal Barrier Coating (TBC) systems consist of a duplex structure with a metallic bond coat and a ceramic, heat-isolative topcoat. For thermal barrier coatings, potential materials like pyrochlore (e.g., La2Zr2O7,Gd2Zr2O7), spinel (MgAl2O4), perovskite (e.g., SrZrO3), or magnetoplumbite (e.g., LaMgAl11O19) structures are being explored. The necessary thermophysical and mechanical properties are being studied.
