Work

The constant increase in the use of implants requires the development of new materials for their manufacture, which would be characterized by high corrosion resistance, biological and mechanical compatibility with human body tissues, sufficient strength and plasticity, low Young's modulus, low magnetic susceptibility and sufficient X-ray contrast. Development of alloys that would meet the above requirements, as well as methods of manufacturing and processing of products (implants) from them, is an urgent and important task, the solution of which will ensure the production of quality medical implants while optimizing the technology of their production. The purpose of this project is to develop a technological approach to the manufacture of biologically and mechanically compatible low-modulus alloys based on the Ti-Zr-Nb system from multicomponent systems of hydrogenated powders; determination of factors influencing hydrogen treatment on the processes of synthesis of alloys to obtain a certain phase composition, microstructure, physical and mechanical properties sufficient for practical use. During the project implementation, the influence of additional hydrogen treatment on the elastic properties of biomedical alloys of Ti-Zr-Nb and Ti-Zr-Nb-Ta systems synthesized from multicomponent powder mixtures will be determined. A new approach to the production of pre-alloyed powders by hydrogen exposure will be developed and recommendations will be formulated for the production of biomedical materials with a given microstructure and physical and mechanical properties. The obtained results can be used to establish industrial production (import substitution) of biocompatible materials for the needs of the medical industry of Ukraine. The results of the work will be tested at international scientific and technical conferences.
