Abstract
We present results of experiments on the action of nanosecond pulsed beams of nitrogen ions and nitrogen plasma on specimens of Ti-4 Al-3 V (wt %) alloy that were obtained using a plasma focus device. Two regimes of material treatment were studied: a high-energy irradiation (with radiation power density of 108 W/cm2), where the surface layer is melted, and a softer irradiation regime (with radiation power density of 107 W/cm2), where a liquid phase on the surface is not formed. The mechanisms of surface modification and hardening of Ti-4 Al-3 V alloy corresponding to different irradiation regimes are discussed.
