NOVOSIBIRSK, may 7 – RIA Novosti. Scientists of the Tomsk Institute of Strength Physics and Materials Science (IFPM so ran) with colleagues from other institutions to develop a bioinert alloys of the new generation of elasticity in human bone for the production of medical implants, the press service of the innovative organizations of Tomsk region.
Era implants: how man is indispensable
The message explains that today the most common material for implants is commercially pure titanium, the modulus of elasticity of about 120 GPA; ceramics – 200 GPA. This is significantly higher than that of human bone tissue, and, therefore, when, installing, implantable, the majority of the load is redistributed on him, which leads to degradation of other bones.
"We are engaged in the alloys of the system titanium-niobium, which is at a certain content of the second component (niobium) have a modulus of about 55 GPA, which is comparable to bone tissue. The output should produce a new biocompatible material with high mechanical characteristics, suitable for the manufacture of any implant", is given in the message of IFPM Ivan Glukhov.

Experts note that the task of obtaining the alloy with the desired properties is the complexity of the melting points of titanium and niobium, therefore, to obtain alloys of these metals.
Materials for research are made together with colleagues from the Institute of Nuclear Physics (BINP), Novosibirsk state tekhuniversitet, as well as with partners in China. Then, the mechanical properties of the material are improved in Tomsk.

"To get the alloy we use various methods of powder metallurgy: electric arc furnace and smelting high-energy electron beam, choosing the best modes and then", explained Glukhov.
Work on the project is planned for two years. During this time, the technological chain of production of the alloy, and then scientists will give material for testing biocompatibility.
