Changing of the Structural-Phase State and Mechanical Properties of VT-23 Titanium Alloy under Surface Treatment by Intense Flux of Copper Ions

Abstract:

Results of surface modification of the VT-23 titanium alloy by high flux of copper ions with an energy of 2 keV and ion current density of 3.5 mA/cm² was studied. The dependence of the microhardness and penetration depth of ion as function of duration of ion treatment was determined. Structural-phase state of ion-modified of the VT-23 titanium samples surface layer was investigated by TEM and SEM. Microhardness was researched by nanoindentation method.
