High quality coatings offer substantial economic and environmental advantages in multiple industries (Bendikiene et al., 2019). High Entropy Hardmetals (HEHs) developed in the context of CoBRAIN project can be applied in many manufacturing industries to protect through coating numerous components of critical materials such as wind turbines, photovoltaics, batteries, vehicles (Mulvaney et al., 2019, Cherrington et. al., 2021) towards the expansion of their lifetime, reduction of maintenance downtime and decrement of component failures. By reducing discarded materials and damaged parts, waste disposal costs are lowered. Additionally, delaying costly replacements and minimising both initial and ongoing expenses lead to a significant reduction in overall costs. Aligned with the circular economy’s goal to extend product lifespans, these durable coatings enhance resource efficiency by reducing the need for new raw materials and minimising industrial waste. CoBRAIN combine AI and computational modeling to enhance coatings in industrial components for particular end – uses, guaranteeing high durability while minimising environmental effects. These advanced coatings also assist industries in achieving EU sustainability targets by lowering energy consumption during manufacturing and maintenance, thereby reducing CO2 emissions, energy use, and raw material usage.
