摘要：
Phase composition and mechanical properties changes of the titanium surface layer nitrided and alloyed by chromium under the action of compression plasma flows have been investigated. The findings showed the formation of an alloyed layer with the thickness of up to 27 mu m containing alpha-Ti, alpha'-Ti and beta-Ti(Cr) phases. The volume fraction of these phases was dependent on treatment regimes. The titanium nitride formation in the surface layer was observed. Treatment by compression plasma flows allowed to increase 2.5 times the surface layer microhardness and to diminish 4.2 times the friction coefficient.
