High-Performance Materials for Next Generation Thermal Barrier Coatings in the System ZrO2-HfO2-Y2O3-Ta2O5
Thermal barrier coatings (TBCs) are widely used to protect hot components from high temperatures and aggressive conditions of gas turbines and diesel engines. The ZrO2‑HfO2‑Y2O3‑Ta2O5 material system promising properties for future TBCs in comparison with the state-of-the art materials.
Multicomponent equimolar oxides for high-performance materials for future application in thermal barrier coatings (MEO-TBCs)
Thermal barrier coatings are used for the protection of the metallic parts in the hot zones of airplane turbines. High-entropy zirconates have a low thermal conductivity and thus are a promising material which can be applied in this field.
Development of high-entropy oxides as new thermal barrier coatings
Synthesis and characterization of High-entropy Oxides (HEOs) via solid state and wet chemical synthesis. The focus is to reduce the amount of rare earth elements and/or zirconium used, and to investigate their physicochemical properties. In cooperation with the University of Bayreuth, these HEOs will be used as novel thermal barrier coatings on a novel SiCr alloy substrate.
High-entropy Li-garnets as new solid-state electrolytes in Li-ion batteries
Synthesis and Characterization of Multi-component Li-Garnet-Oxides using solid-state and wet chemical synthesis approaches. The focus of this work lies on the research of component-property relations. Key measurement tools are XRD and thermal analysis.
Thermal safety analysis of sulfide solid-state batteries
Investigation of sulfide solid-state batteries to assess thermal stability and the resulting safety factors using simultaneous thermal analysis (STA) and calorimetry. The highlight of the project is the possibility of analysing the thermal properties of the assembled cells while charge-discharge cycling.
Cathode Materials for Mg batteries – Mg-garnets
Development of various synthesis strategies for the production of Mg-garnets and subsequent characterisation using x-ray diffraction, electron microscopy and x-ray photoelectron spectroscopy.
