Abstract
The research aims to modify the process of obtaining galvanic composite coatings based on zinc.The model used the usual parameters of the deposition process: current density, temperature, deposition time, and electrolyte composition.The novelty of the research is the gradual combination of surfactants in the electrodeposition process.At the first stage of obtaining a zinc coating, known additives (gelatin, thiourea) were used in the electrolyte at current densities of 0.5-3 A/dm 2 .At the second stage, already on the obtained zinc coating, deposition from an electrolyte of similar composition was performed again, but using a surfactant (the conditional name of BGU-21)the product of oil synthesis [R 2 POHC(S) (NH 2 )], having a high adsorption capacity and good solubility in the electrolyte.
