Investigation of Surface Layers of Titanium Alloy VT6 with Deposited Carbon Film under Ion-Beam Stirring

The surface layer obtained by ion-beam stirring of a thin carbon film deposited on titanium alloy VT6 is studied. The composition and the chemical condition of elements in the surface layer are determined. Formation of a disordered carbon structure in a thin surface layer (20 – 40 nm) and of titaniu...

Description
Summary:The surface layer obtained by ion-beam stirring of a thin carbon film deposited on titanium alloy VT6 is studied. The composition and the chemical condition of elements in the surface layer are determined. Formation of a disordered carbon structure in a thin surface layer (20 – 40 nm) and of titanium carbides in the transition layer is detected. A model of formation of structure in the specimens during irradiation is developed. It is shown that formation of a disordered carbon structure, of titanium carbides, and of dislocation substructures is responsible for elevation of the microhardness of the specimens after ion-beam stirring.
