The aim of this paper is to briefly analyze different methodologies for development of novel materials systems and coatings for use in extreme environments, with a focus on high-temperature applications in aerospace and aeronautics. The approach is based on a comparative analysis of selected major thermal stability properties of different material systems (mainly transition-metal oxides and carbides) used in thermal protection systems and how different existing coating methods can be used as best available technologies to implement these new materials in high-temperature coatings. Finally, an original example of high-temperature coatings based on barium and lanthanum zirconates with perovskite structure obtained by electron beam vapor deposition is presented.
