Currently funded project

The project objective at HTL is the development of novel coatings to reduce the thermal and corrosive degradation of the refractory material in a tunnel kiln. The focus is on metallic and ceramic coatings with complex entropy-stabilised compositions, so-called Compositionally Complex Alloys CCA or Ceramics CCC. The compositions will be developed by a combination of AI and ML methods, computational chemistry, thermodynamic considerations and high-throughput experiments. For in-situ sensing, luminescent elements will be added.

• Pre-selection of suitable oxides for CCC based on experience and literature research
• Preparation of systematically varied compositions via sol-gel route, drying, pulverisation and sintering
• FactSage calculations for phase stability
• Evaluation of coatings by means of μ-CT, XRD, density and optical appearance as well as calculated thermo-physical properties using AI and ML methods
• Selection of potential compositions for corrosion experiments
• Transfer of the sol-gel process to slip-based processes
• Spray coating of refractory material
• Application of the coating in the furnace
