Siberian scientists have found a way to increase the strength of titanium implants seven times

Scientists from Tomsk State University have developed an innovative method for increasing the strength of titanium implants. New technology increases the corrosion resistance of medical alloys by seven times.
As RIA Tomsk reports, the researchers used the “high-dose ion implantation” method – they irradiated alloys based on titanium nickelide with beams of niobium ions. A protective oxide film has formed on the surface of the material, which serves as a barrier against aggressive environmental influences.
The development is of particular importance for medical products with shape memory – self-expanding stents and orthodontic arches. Increasing their corrosion resistance increases their service life and reduces risks to patients.
The development will make it possible to create materials with the properties of “metallic glass” without extremely high cooling rates, which previously limited the possibilities of using such alloys in medicine.
