Данная работа посвящена исследованию влияния смешанных слоев W–C на изменение морфологии поверхности и структурно-фазовых состояний поверхностного слоя вольфрама при воздействии D плазмы. Эксперименты по карбидизации и плазменному облучению проведены на плазменно-пучковой установке (ППУ) при различных энергиях ионов и температурах поверхности. В качестве рабочего газа при карбидизации использовался метан (CH4), при плазменном облучении – дейтерий. Воздействие D плазмы с энергией ионов 1 кэВ на поверхность вольфрама со смешанными слоями привело к полному разрушению карбидных соединений при температуре ~1750 °С и дальнейшей эрозии вольфрама. Однако, при температуре ~900 °С смешанные слои на основе двух фаз (WC и W2C) обладают высоким сопротивлением дейтериевому воздействию.

This work is devoted to studying the effect of mixed W–C layers on the change in the surface morphology and structuralphase states of the tungsten surface layer under the influence of D plasma. Experiments on carbidization and plasma irradiation were carried out on a plasma-beam installation (PBI) at different ion energies and surface temperatures. Methane (CH4) was used as a working gas during carbidization, and deuterium was used for plasma irradiation. The effect of D plasma with an ion energy of 500 eV on the tungsten surface with mixed layers led to the destruction of carbide compounds at a temperature of ~1750 °C and further erosion of tungsten. However, at a temperature of ~900 °C, mixed layers based on two phases (WC and W2C) have a high resistance to deuterium action, as evidenced by an insignificant change in the phase content.
