After processing the firmness of alloy was increased up to 40-42 un. HRC in comparison with 28 un. HRC in hot rolling condition. Friction coefficient of VT6 alloy head on extra high molecular polyethylene was similar to the friction coefficient of Co-Cr-Mo alloy head. Wear of extra high molecular polyethylene in couple with titanium-alloy was 5 times lower than in couple with Co-Cr-Mo alloy. Surface hardening of VT6 alloy by thermal-hydrogenous processing 10 times decreases the wear of bone cement at friction. On the base of experimental study the new cemented hip endoprosthesis «SFEN» was elaborated.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic>Проведены экспериментальные исследования по изучению влияния термоводородной обработки на структуру, механические и трибологические свойства титанового сплава ВТ6.
