Development of bio-functionalized and tribocorrosion resistant hybrid surfaces on novel Ti-based alloys - BIOHYB

Project summary

Titanium and its alloys are the most commonly used materials in orthopaedic and dental implants. However, some major clinical concerns are still valid, namely bone resorption due to stress shielding, low tribocorrosion resistance (leading to the intense release of metallic ions and wear debris, with local and systemic harmful effects) and lack of bioactivity. The overall objective of the BIOHYB project is to find solutions to these major clinical concerns by using low Young’s modulus TiNb alloys, in which tribocorrosion-resistant hybrid and bio-multifunctional surfaces will be created. Multifunctionalized functionally graded materials (FGMs) will be developed by following two innovative and original strategies: (i) bio-FGMs having tribocorrosion resistant TiB/TiN/TiC-rich graded hybrid surfaces containing antimicrobial and bioactive agents, (ii) bio-functionalized hybrid coatings having tribocorrosion resistant TiB/TiN/TiC hybrid surfaces containing antimicrobial and bioactive agents.
