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.
