Thermal Barrier Coatings: Simulation, Modeling and Other Methods of Operating Properties’ Prediction

Dear Colleagues,

Numerical simulations and model tests allow for effective prediction of thermal barrier coating (TBCs) systems properties, without the high cost associated to actual production. In recent years, many new material proposals have appeared that could serve as an alternative to the commonly used 8YSZ. Among them, particularly important are materials with a pyrochlore or fluorite structure, hexaaluminates, perovskite and rare earth niobates and tantalates. Various internal construction systems variants are also analyzed: DCL (double ceramic layered), FGS (functionally graded system), multilayered or composites. As TBC materials work in a very demanding environment, they must characterize a complex combination of physicochemical properties. The development of ceramic materials at TBCs will allow implementing new construction solutions, among others, in aircraft engines, increasing their performance and the durability of their components. In addition to the aspect of searching for materials with minimal thermal conductivity, it is necessary to take into account the interrelation of connected compounds and the working environment, i.e., high temperature, oxidizing atmosphere, the interaction of liquid salt and vitreous deposits. Most of the listed properties of materials can be determined and predicted based on model tests and numerical simulations. More expensive tests on ready components can be carried out only on the potentially best variants selected.

This Special Issue on “Thermal Barrier Coatings: Simulation, Modeling and Other Methods of Operating Properties’ Prediction” intends to collect the latest developments in the field in the form of papers written by well-known researchers who have contributed significantly to computational modeling, numerical simulation, or material characterization of thermal barrier coatings based on new material and construction solutions.

Topics addressed in this Special Issue may include but are not limited to:

• Computational modeling, numerical simulation and prediction of TBC properties;
• Finite element method;
• First principle calculation:
• Model investigations in area of:
  • Thermochemical stability;
  • Thermal properties;
  • Mechanical properties;
  • Hot corrosion behavior;
  • Corrosion in glassy CMAS- and AVA-type deposits.
