The work is devoted to the study of the influence of the parameters of electrodeposition and the composition of the electrolyte on the superhydrophobic properties of zinc coatings. As is known, the superhydrophobic (SHP) properties of the material are given by micro and nano roughness of the surface in combination with treatment with substances that reduce surface tension. Therefore, special attention was paid to the study of the morphology of surfaces obtained from different types of galvanizing electrolytes - acid and alkaline, including for composite zinc coatings. It was concluded that superhydrophobic zinc coatings are obtained in the case of an acidic pH only when adding nitrate ions to the solution. In alkaline solutions, it was not possible to obtain SHP zinc coatings without additional additives. In the case of composite zinc coatings, coatings made of acidic electrolytes are the most optimal in terms of the quality and properties of SHP.
