TPU scientists improved the properties of high-entropy ceramic coatings for aviation

Scientists at Tomsk Polytechnic University have found out how to improve the properties of new high-entropy ceramic coatings to be used at ultrahigh temperatures and in aggressive environment. TPU researchers have managed to achieve increased resistance of carbide materials to oxidation at 1100°C. In the future, such coatings can be used for aviation and aerospace equipment elements, notes a press communiqué from the University.

The results of the research, supported by the Russian Science Foundation grant, are published in Ceramics International.

TPU scientists are working on the development of fundamentally new multilayer coatings that can significantly increase their operation temperature range. Coatings based on oxides of hafnium, zirconium, cerium, and yttrium were synthesized earlier. The magnetron sputtering method is used for their application. The synthesis and investigation of the properties of high-entropy materials based on carbides has become the next stage of the research.
