RISE - Rapid In-situ Synthesis of High Entropy Oxides for Next-Generation Thermal Barrier Coatings

The goal is to bridge the gap between the exceptional properties that have been demonstrated by bulk HEOs from prior research by various groups and their practical applications in the form of coatings, such as thermal barrier coatings (TBCs) for gas turbines and electrodes for solid state batteries. HEOs are a new class of ceramics comprised of multiple metal cations, typically in equiatomic ratios, randomly distributed within an oxygen anion lattice. The high configurational entropy of HEOs promotes phase stability and imparts favourable thermo-physical properties. Thermal spray processing offers a versatile platform with a broad range of tuneable parameters that can be exploited to conveniently deposit innovative HEO coatings. The specific novelty of the present approach lies in novel in situ synthesis of HEOs with different chemistries during spraying rather than relying on availability of reasonable amounts of these HEOs in powder form as feedstock.

The project will be primarily conducted at University West, Sweden, which offers strong expertise and infrastructure in thermal spray processing. A secondment at the Institute of Plasma Physics in the Czech Republic will provide access to advanced deposition and characterization tools. Additionally, a non-academic placement at Treibacher Industries in Austria will offer industrial exposure and resources to explore the commercial potential of the work. Through this project, the researcher will gain hands-on experience with state-of-the-art equipment, participate in interdisciplinary collaborations, and develop a well-rounded perspective on both academic and industrial applications—laying a strong foundation for their future career.
