Abstract

The results of structure and phase composition change in tungsten after compression plasma flow and high-intensive pulsed ion beams impacts are discussed. The compression plasma flows with the absorbed energy in range 35–70 J/cm2 were used for the sub-surface modification. The preliminary Ti coating deposition on the tungsten surface allowed us to form W-Ti alloys by plasma flows treatment. The layer of the W-Ti alloy consists of solid solutions W(Ti) and β-Ti(W) as well as nitride phase (Ti,W)N. The high-intensive pulsed ion beam impact provides the tungsten carbide W2C formation in the sub-surface layer. When forming the W-Ti alloy the carbon ions implanted into the tungsten take part in the carbo-nitride (Ti,W)(N,C) formation without brittle W2C phase.
