Biocompatible Ti-Nb alloys produced via relativistic electron beam in air atmosphere

Abstract

In present paper Ti-Nb alloys produced via high-energy powder metallurgy method were studied. Ti-Nb alloys were obtained in form of layers on Ti substrate. The energy source was an electron beam emitted to the atmosphere, penetrating into deep layers of the powder. Electron energy was 1.4 MeV. It is shown that it is possible to produce alloys with predictable elemental and phase compositions via relativistic electron beam. Depending on the content of Nb, such phases as α′, α″ or β are formed. Produced alloys are non-toxic for cells. Due to this, manufacturing of small medical implants from this material is possible.
