Influence of technological factors on porosity in the mass production of inlet guide vanes using additive technologies

Abstract

Stainless steel products manufactured using additive technologies are widely used in many branches of modern industry (aviation, medicine, engineering, etc.). One of the main defects in this type of production is porosity. Surface treatment with high-current pulsed electron beams (HPEB) allows not only to increase microhardness and corrosion resistance, but also to reduce surface roughness and porosity in the recrystalized layer. This article presents studies of the microstructure of stainless steel samples, as well as the structural and phase state of the surface layer of samples before and after irradiation with HPEB.
