Abstract

A study was carried out of the dependence of the characteristics of strength and ductility of structural steel 10G2 samples on the modes of laser surface hardening and alloying with a fiber laser. On the opposite planes of a sample with overall dimensions of 6×20×200mm, 5 tracks were applied. Samples were tested for static destruction. It was established that the destruction of the treated samples in all cases was of a viscous nature with a satisfactory level of destructive deformations at stresses above the strength limit of the original material. Tensile diagrams indicate an insignificant effect of laser treatment on the elastic modulus of the material. The results obtained can serve as a basis for studying the relationship between laser beam heating modes and the material properties of the strengthened zone.
