Strategies for the Development of Environmental Barrier Coatings for High-Temperature Applications

Ceramic coatings provide an excellent protection of components, which are applied in harsh environments.They can withstand high temperatures and corrosive media and form an excellent barrier against reactivemolecules and heat. Due to complex requirements, multiphase and multilayer coating systems are developed.A systematic approach for material selection as well as microstructure-, layer- and process design isrequired … Weiterlesen …

High Temperature Ceramics for Light-Weight Kiln Furniture

Alumina- and mullite-based materials for kiln furniture application of up to 1700 °C have been successfully developed. The materials show significantly improved thermomechanical properties in comparison to commercial benchmark products permitting the design of kiln furniture with reduced mass. This leads to significant energy savings in high temperature processes. It is demonstrated that the achieved … Weiterlesen …
