Effect of the rolling on the VT22 titanium alloy structure and wear resistance is investigated. As shown, a load increase during the deformation treatment increases the level of near-surface strengthening and improves surface quality. As experimentally determined, the rolling of VT22 alloy leads to both the $\alpha$-phase grain refinement and the increase of the density of fixed dislocations in the near-surface layers of material. As shown, the VT22—BrAZhN 10-4-4 friction pair with titanium alloy disc rolled under loading of 200 N has the best suite of tribological characteristics.

Key words: structure of near-surface layers, adhesion wear, plastic deformation, rolling, VT22 titanium alloy.
