Abstract

Data on the study of the formation of zinc intermetallic diffusion layers on thermally hardened surfaces under conditions of structural change of the metal are presented. For zinc diffusion layers formed on a martensitic steel base, an increase in the values of microhardness and the zone of formation of a solid solution of zinc in iron (α-phase) was observed in comparison with zinc diffusion layers formed on steel with a pearlite structure.
