摘要：

Specimens of steel 70 are studied before and after alkaline galvanizing and after galvanizing and partial dehydrogenizing. The content of hydrogen and its distribution between the coating and the substrate are estimated. The structures of the substrate metal and of the coating are studied before and after dehydrogenization. Mechanical tests at various rates of deformation of specimens of steel 70 in different initial states are performed. The tests are followed by an analysis of fracture surfaces. The effect of hydrogen on the fracture behavior is evaluated at different rates of deformation of specimens. The effect of reversibility of the structure and properties in "hydrogen charging-dehydrogenization" of the steel is determined and the mechanism of formation of a layered structure of zinc coatings is described.
