Abstract:
The physicomechanical properties of the VT1-0 titanium surface modified by a pulsed carbon ion beam at a pulse duration of 80 ns, an energy of 200 keV, a current density of 120 A/cm$^2$, an energy density of 1.92 J/cm$^2$, and various numbers of pulses (four regimes) are studied. Irradiation by the beam leads to hardening of a 1.8-$\mu$m-thick surface layer in titanium, a decrease in the hydrogen sorption rate, a decrease in the grain size, and the formation of twins.
