Abstract

The research project to be developed during the period as visiting researcher at the Institut National Polytechnique de Grenoble, INP-Grenoble, at the Laboratoire d' electrochimie et de physico-chimie des matériaux et des interfaces, LEPMI, and Laboratoire Science et Ingénierie des Matériaux et des Procédés, SIMAP, is focused on the current research activities of the proponent in metallic alloys with microstructures containing amorphous, metastable and nanostructured phases, and has the objectives to use the facilities and expertise of the researchers at LEPMI and SIMAP to evaluate relevant properties in some specific systems belonging to this class of metallic materials. The first focus of research will be the evaluation of newly developed metallic alloys to be used as optimized coating applications. Such alloys include different families of high-entropy or pseudo-high entropy alloys, with compositions related to Fe-based B-containing commercial steels, and designed to improve the ability to form amorphous phase and to improve corrosion resistance even after partial crystallization. The second focus of research will be associated with the development of biocompatible ultra-fine grained ²-Ti-based alloys to be used as human implants, their surface modifications to induce specific responses on osteoblastic and immune cells after implantation and detailed electrochemical characterization including in vitro corrosion tests to verify the dissolution of metallic implants. For both types of systems, which we are proposing to study, the interactions with SIMAP researchers with expertise in alloy design and with LEPMI researchers with expertise in electrochemical characterization are considered one of the strongest aspects to assure the successful development of this research plan.
