Electron-Beam Surface Processing of Metal Materials Manufactured by Additive Methods

method for finishing the surface of metal materials manufactured by additive technologies with an intense pulsed electron beam, which can be an alternative to traditional processing methods, is presented. The optimal irradiation modes for VT6 titanium alloy specimens manufactured by metal powder fusion and 308LSi stainless steel specimens manufactured by electron beam welding are determined. It is shown that the presented processing method leads to a visual decrease in the porosity and a multiple decrease in the surface layer roughness (R a ) (by 20 times) of the VT6 titanium alloy manufactured by the additive method. The surface roughness of 308LSi stainless steel specimens manufactured by electron beam welding decreased by a factor of 2.1 in the longitudinal direction and by a factor of 5.2 in the transverse direction relative to the surfacing plane. It has been shown that the elemental composition, strength, and tribological properties of the specimens do not change after irradiation in optimal modes. Tensile testing of irradiated specimens revealed an increase in the tensile strength by 12% and in the ductility by 10% (VT6) and the anisotropy of the mechanical properties depending on the direction of tension relative to the surfacing plane (308LSi).
