Surface effects under nitrogen ions and nitrogen plasma flows treatment of Ti-Al-V-system alloy
Ti - 4 Al - 3 V alloy was irradiated with nanosecond pulsed nitrogen ion and plasma beams in Plasma Focus device. The two different modes of the treatment were applied: high power density (108 W/cm2) irradiation with melting of the surface layer and irradiation with power density (107 W/cm2) below melting threshold. Mechanisms of modification and hardening of the surface layer of the Ti - 4 Al - 3 V alloy under applied irradiation have been discussed.
