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 m after the HIB effect: 300 pulses 9 10^–2 m long with a summary energy density of 430
J/cm². The features of the CPF treatment are a larger time of pulse effect (100 s) and the preferential convec-
tion agitation of the molten layer. As a result, a thicker layer of the (W, Ti)C solid solution with uniform ele-
mental distribution over the depth and high hardness (30 GPa) is formed.
