Abstract

The change in the morphology, phase composition, hardness of surface layers, microstructure, and elemental composition of the inner layers of an alloy under the effect of high-power pulsed ion beams (HIBs) and compression plasma streams (CPSs) is investigated. It is found that the thickness of the molten surface layer increases to 3–4 μm after the HIB effect: 300 pulses 9 × 10−2 μm long with a summary energy density of 430 J/cm2. The features of the CPF treatment are a larger time of pulse effect (100 μs) and the preferential convection agitation of the molten layer. As a result, a thicker layer of the (W, Ti)C solid solution with uniform elemental distribution over the depth and high hardness (30 GPa) is formed.
