Abstract
The article presents the results of a study of the Ni-Fe system coating on a 09G2S (Fe-Mn9% Si2%) steel substrate obtained by laser surface treatment. The coating was obtained in two stages. At the first stage, a precursor coating (PC) of Nickel was applied by cold spray (CS). At the second stage, its surface was laser treatment. The article shows changes in the composition and properties of the coating after laser treatment at different thicknesses of the precursor coating and different laser treatment modes. The results of the study showed that the composition and structure of the coating can be controlled by controlling the thickness of the precursor coating, the scanning speed, the scanning hatch, and the number of repeated scans.
