FIELD: metallurgy.
SUBSTANCE: product surface with initial roughness is affected by a pulsed beam in vacuum at a pressure of (2-5)⋅10-2 Pa, electron energy of 15-25 keV, pulse durations of 150-200 mcs and energy density in pulse of 40-60 J/cm 2.
EFFECT: decreased porosity and roughness of the surface layer of bulk metal products.
