ABSTRACT
The article presents the results of an experimental study of surface roughness in C45 steel cylindrical specimens treated by electron beam surface hardening. The effects of technological parameters: electron beam current Ib (mA), peripheral velocity Vw (m/s), focal length FL (mm), and scanning frequency SF (Hz) on the treated surface were investigated in terms of the 2D roughness parameter Ra using a one factor-at-a-time technique. It was found that the factors with the greatest influence on the resulting roughness are the electron beam current and the peripheral velocity. The minimum roughness values were obtained at maximum scanning frequency and minimum peripheral velocity.
