The effect of combined treatment consisting of severe plastic deformation and ion beam treatment on structure and tribological properties of titanium, zirconium and "Zr - 2,5 % Nb" alloy was investigated. It was shown that formation of ultrafine-grained structure in titanium and zirconium alloys produced by severe plastic deformation results in sufficient increase in materials hardness in 1,6-2 times. Ion modification of deformed titanium and zirconium based alloys ensures further enhancement of surface microhardness up to 3500-3700 MPa, improvement of wear resistance of materials up to 30 times and reduction of friction coefficient by 50 %. Based on the results obtained it was shown that Ti- and Zr-based alloys processed by combined treatment consisting of severe plastic deformation and ion-beam nitriding may be regarded as a promising materials for production of biocompatible high-loaded orthopedic implants.
