Descripción del proyecto
Una herramienta inteligente acelera el descubrimiento de revestimientos de metal duro de alto rendimiento
La pulverización térmica produce revestimientos de metales, aleaciones, cerámicas, plásticos y materiales compuestos mediante la proyección de polvos fundidos o calentados sobre superficies. Entre los materiales de revestimiento disponibles, los metales duros ofrecen una excelente resistencia al desgaste y la corrosión. Sin embargo, los revestimientos actuales de metales duros se basan en elementos críticos (Co, W). Además, sus propiedades suelen optimizarse mediante métodos de ensayo y error que son caros. Crear una herramienta de selección fiable basada únicamente en datos empíricos sería demasiado engorroso. Incluso el uso de modelos físicos basados en microestructuras para predecir sus propiedades llevaría mucho tiempo. El objetivo del proyecto CoBRAIN, financiado con fondos europeos, es resolver estos problemas integrando datos computacionales y empíricos con inteligencia artificial mediante la interoperabilidad semántica. El equipo de CoBRAIN desarrollará una herramienta inteligente para proponer tecnologías novedosas a partir de la clase de metales duros de alta entropía libres de materiales críticos.
Objetivo
Wear and corrosion protection play a crucial role in the effort of European Manufacturing Industries to maximise both efficiency and productivity because they are inherently related to the lifetime of the components and their manufacturing cost. Thermal Spray technologies for the deposition of Hardmetals were developed for this reason, i.e. specifically to provide higher resistance to sliding and abrasive wear, coupled with good corrosion resistance. In this field innovation is based on experimental trial-and-error and operational feedback, because the equations that can model the coating performance have to consider the mechanical properties of the hard phase and those of the metal binder, their microstructure and interaction, and their evolution during the non-equilibrium Thermal Spray process. The final coating properties depend on all these factors and more, and they are too many for a physical modelling workflow to provide reliable results on a time scale that is compliant with industrial responses to fluctuating markets, supply chains and regulations. On the other hand, tools based on experimental data that rely only on final coating macro properties require extensive datasets to be reliable. This again conflicts with the response time required by industrial innovation. Moreover, innovation in coating technology is not just a matter of performance and costs: industrial companies have to consider multiple other factors such as the impact on workers, hidden regulatory costs, environmental protection costs, and also general public opinion. CoBRAIN offers a solution to this need, exploiting the integration of computational and experimental data through semantic interoperability, and developing an intelligent tool that will be able to propose novel materials from the class of High Entropy Hardmetals for direct deposition by HVOF, HVAF and CGS Thermal Spray, and capable to estimate their impact on the economy and the environment.
