The structure and phase composition of the surface layer of the samples during the processing of VT-10 titanium alloys by copper ions

The phase composition, structure and morphology of the surface of VT-10 titanium modified by copper ions have been investigated by X-ray, SEM and TEM. It has been established that there are intermetallide phases of Cu-Ti equilibrium diagram in the surface layer during the treatment of VT-10 titanium...

Description
Summary:The phase composition, structure and morphology of the surface of VT-10 titanium modified by copper ions have been investigated by X-ray, SEM and TEM. It has been established that there are intermetallide phases of Cu-Ti equilibrium diagram in the surface layer during the treatment of VT-10 titanium by copper ions. The modified surface layer in the cross section is divided into two layers: up to 1 µm in thickness and from 1µm up to 4.5–5.0 µm, depending on the treatment time. Two-level micro and nanoporous nanocrystalline structure was formed in the modified layer. It was found that the phase structure and the morphology of the surface layers of VT-10 alloys depend on the treatment time.
