The formation of nanoscale layers on the VT6 titanium alloy surface by ion-beam mixing of carbon with the N+ ion implantation is investigated in this work. Ion-beam mixing in the transition layer of a film–carbon system on the VT6 alloy surface has been found to provide conditions for the formation of titanium carbides and nitrides. The thin surface layer (~10–20 nm) of the samples after both the deposition and ion-beam mixing of a carbon film mostly consists of carbon in a disordered state with sp2 and sp3-hybridized C–C bonds. The formation of titanium carbides and nitrides in the transition layer, a disordered carbon structure in the thin surface layer, leads to a tenfold increase in the corrosion resistance of the samples.
