Technical Symposium MA
Symposium MA focuses on surface engineering and materials science of protective and high-temperature coatings. The interaction of coating materials with harsh environmental conditions is addressed, including high temperatures, thermochemical environments, as well as mechanical loads. The environmental impacts include phenomena such as thermomechanical wear (e.g., abrasion, erosion, or mechanical stress), high-temperature aging, corrosion (e.g., oxidation, sulfidation, carburization, and water-accelerated degradation), or catalytic and physical fouling (e.g., coking, ash fouling, and slagging). The symposium also addresses coating deposition processes, architectural designs, and process-structure-property relationships of protective coatings. The protective coating materials range from metallic alloys to ceramics such as nitrides, borides, oxides, or carbides. Furthermore, specific alloying strategies such as high entropy alloys (HEAs) and other multi-principal-element materials, which obtain unique chemical and physical properties, are of interest. The application areas span the energy generation, the aviation sector as well as the machining industry, highlighting new developments towards zero GHG emission and sustainability.
MA1. Coatings for High Temperatures and Harsh Environment Applications
This session focuses on the design, development, synthesis, and performance of coatings intended to resist high-temperature oxidation, corrosion, and fouling. This includes protective coatings as well as thermal and environmental barrier coatings, which are crucial components in advanced technologies such as steam, gas and hydrogen turbines, jet engines, concentrated solar power plants (CSP), advanced nuclear reactors, petrochemical and gasification plants, waste incinerators, metal-forming, recycling industries and solid oxide fuel cells (SOFC) and electrolysers (SOEC) for hydrogen production. The demand for effective solutions is heightened in harsh environments characterized by exposure to steam, supercritical carbon dioxide (SCO2), molten salts, liquid metals, hydrogen, ammonia, biofuels, and similar substances. The research challenges involve coating development, process optimization, and the exploration of innovative processing techniques. Key areas of focus include the characterization of coatings and reaction products, understanding degradation mechanisms, modelling fabrication and degradation processes, and assessing the lifetime and performance under operationally relevant conditions (including atmosphere, stress, cycling, erosion, abrasion, and CMAS attack).

MA2. Hard and Nanostructured Coatings
This session welcomes contributions related to the characterization, simulation, development, and application of hard coatings and surfaces, including the relationships among composition, microstructure, chemical and mechanical properties, and the influence of deposition conditions on those parameters. The session also covers multifunctional nanostructured coatings, including nanocomposite, multi-component, and layered films with designs adapting the microstructure down to the nanoscale level. The session emphasizes the design, synthesis, and characterization of novel coating concepts, their modelling, and applications, as well as the development and use of novel characterization techniques, bridging both theoretical and practical aspects of hard and smart coatings.

MA4. Boron-containing Coatings
Borides and boron-containing thin film materials are emerging as the next generation of hard, wear, oxidation-, and corrosion-resistant coatings. Furthermore, various boron-based materials exhibit unique properties, obtaining high potential for functional and architectural designs. The aim of this session is to provide a platform for first-principles design, synthesis, characterization of properties and defect structure, as well as applications of different types of boron-containing protective and functional thin films.
