Biocompatible titanium-based alloys for medical prosthetics from complex microalloyed systems
Project Details

Design, elaboration and investigation of new, original biocompatible alloy systems, the new variant of alloys contains different values ​​of the alloying percentage of non-toxic elements (Mo and Si) in order to improve the mechanical properties (mechanical strength, modulus of elasticity), alloys that have a good corrosion resistance and biocompatibility corresponding to.

Specific objectives:
  • Designing, obtaining, and testing of Ti-Mo-Si type alloys for medical applications, with the ultimate goal of promoting a new generation of titanium alloys;
  • Employing 2 young researchers with full time (TUIASI și INCDFT-IFT IAȘI);
  • In vitro biocompatibility study, implantation, osteointegration study, and resorption rate on animal experimental model;
  • Testing and complete characterization of biomaterials obtained for patenting;
  • Dissemination of results, attracting the interest of implant manufacturers to create medical devices from the new alloy system.
  • Obtaining and structural characterization of at least eight Ti-based alloys with Mo and Si alloys with medical applications;
  • Determination of functional properties and biocompatibility in vitro and in vivo of orthopedic alloys in the Ti-Mo-Si system;
  • Evaluation of experimental results on the Ti-Mo-Si alloy system;
  • Identifying an optimal Ti-Mo-Si ideal composition for orthopedic implants and identifying a global composition of the Ti-Mo-Zr-Ta-Si complex system;
  • Publication of at least 6 articles in ISI-indexed journals, development of at least two new patents and participation in international exhibitions, fairs and salons of research.
