Abstract:
The article is devoted to the implementation of the process of electrochemical 3D printing of zinc products and the
determination of the effect of the method of their production on corrosion resistance. The possibility of electrochemical 3D
printing of zinc objects with a fine-crystalline compact structure using high-speed sulfate plating electrolyte has been shown.
The most resilient and elastic zinc deposits were obtained in the electrolyte without the addition of organic additives and when
gelatin was added to the electrolyte. The use of naphthalene disulfonic acid of 1,5-disodium salt made it possible to obtain the
most finely crystalline and semi-glossy zinc deposits, but the fragility of the deposits increased somewhat. Conducted studies
of the corrosion resistance of printed zinc objects showed that the use of electrochemical 3D printing as a method of obtaining
and introducing organic additives into the electrolyte does not lead to a decrease in the corrosion resistance of the metal.
