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 energy generation, the aviation sector, as well as the machining industry, highlighting new developments towards zero GHG emissions 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.

MA3. High Entropy and Other Multi-Principal-Element Materials
High entropy alloys (HEAs) and other multi-principal-element materials are multi-component systems in which high entropy of mixing, or kinetic effects, stabilize a solid solution. They exhibit unique chemical and physical properties and have therefore recently attracted a growing interest in the materials science community. This session will be a platform for thin film-related research on high-entropy and multi-principal-element materials, including metal alloys, carbides, nitrides, and oxides, as well as other multi-component systems in which high entropy affects phase stability. Topics of interest include but are not limited to modelling, thin film processing, and characterizations of HEAs and other multi-principal-element materials.

MA4. Boron-containing Coatings
Boride-based and boron-containing thin films are at the forefront of materials science due to their exceptional combination of properties. Renowned for their high hardness and superior resistance to wear, oxidation, and corrosion, these coatings provide critical protection in demanding operational environments. Furthermore, their unique optical, electronic, and thermal properties make them highly promising for a wide range of functional applications.
This session will bring together researchers, engineers, and industry professionals to share and discuss the latest developments in boride-based coatings and materials. The goal is to create a collaborative platform to explore and understand these materials, from initial concepts to practical implementation, by addressing key challenges and opportunities in the field, aiming to accelerate the development and application of advanced boride-based coatings. We welcome contributions on topics including, but not limited to: Synthesis and deposition, Advanced characterization, Applications, and Computational design.
