Alkaline-cyanide electrolytes of galvanizing have a good scattering ability, which creates conditions for obtaining high-quality zinc coatings due to the formation of soluble complexes of sodium cyanide and caustic sodium alkali, which can ensure the stability of the electrolyte and the constancy of the composition of the cyanide electrolyte. These conditions cause additional difficulties associated with regulating the composition of the electrolyte. The disadvantage of cyanide alkaline electrolytes of galvanizing is also a high sensitivity to a number of impurities in the electrolyte, the release of which is associated with difficulties. We have studied the effect of surfactants (thiourea derivative of dialkylphosphorous acids) on the scattering ability of an alkaline electrolyte capable of producing zinc coatings in the current density range of 0.5-3.5 A/dm2, at a temperature of 20°C, with confirmation of the quality of the obtained coatings by energy dispersion and electron microscopic analysis on a JSM-6490LV scanning electron microscope with INSAEnergu energy dispersion microanalysis and HKL-Basic structural analysis with a useful magnification of 300.
