In this work, the effect of vacuum ion-plasma treatment on the wear resistance of the medical screws surface made of VT6 titanium alloy is studied as well as on the mechanical characteristics of the screws in contact with the plate for osteosynthesis. It is shown that the TiN titanium nitride deposition on the screw head increases the surface microhardness by 3 times and also provides lowering the torque during removal of the screw out of the plate.
