| Popis: | This paper is reviewing published data on a substantiation of using zirconium alloys with different phase composition in the strain-hardened condition as biocompatible materials. The recent studies of the impact of the structural state of the surface layers of zirconium alloys at their relaxation and corrosion resistance are analyzed. Special attention is paid to the mechanism of formation of ultradispersed and nanosized grain structures, texture, and mechano-chemical reactions of formation of oxide layers under the influence of ultrasonic impact treatment (UIT) by contact-shift scheme. The reasons of the positive impact generated when UIT of ultradispersed grain structure and oxide layers on microplastic deformation resistance and corrosion resistance of Zr alloys are also explained. |
