Researchers of NSTU participate in the development of the material that is the most similar to human bones. In the future, this material is planned to be used for the production of medical implants. The first products from the new material will be presented approximately in 2020.
Scientists of the Institute of Strength Physics and Materials Science of the Siberian Branch of the Russian Academy of Sciences (Tomsk) have set the task of obtaining a bioinert alloy with a low modulus of elasticity. Materials for research are produced jointly with colleagues from Novosibirsk State Technical University, the Institute of Nuclear Physics (INP SB RAS), and with the help of partners in China. Then, the mechanical characteristics of the obtained material are improved in Tomsk.
"We are engaged in alloys of the titanium-niobium system, which at a certain content of niobium have an elastic modulus of about 55 gigapascals, which is comparable to the characteristics of bone tissue. At the output, a new biocompatible material with high mechanical characteristics should be obtained, suitable for the manufacture of any implants," says Ivan Glukhov, a specialist of the Physics Laboratory of nanostructured biocomposites of the IFPM.
The alloy of titanium and niobium was created by the scientists of the Department of Materials Science in Machine Building of NSTU in collaboration with colleagues from the Institute of Nuclear Physics named after. G. I. Budker. Initially, the alloy was created to be used in chemical reactors, as it is extremely resistant to aggressive substances (for example, acids) and can prolong the life of the reactor.
