Head Lytvynov Leonid Arkadijovych, Registration Date 12-03-2002 Organization Department of Optical and Constructional Crystals of STC <Institute for Single Crystals> popup.description2 Friction pairs: sapphire-sapphire, sapphire-ruby, sapphire-ticor, sapphire-metal and sapphire-polyethylene have been prepared. Preliminary study of the friction coefficient was carried out under conditions approximated to those of hip joint operation. The study was performed on certified installations YSO. The results of the measurements show a strong dependence of Kfr. on crystallographic features of the samples and degree of roughness.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
