Terms of use of Surface Active Substances (SAS) To Receive Quality Galvanic Coatings of Zinc

Abstract

The use of metal galvanic zinc coatings for protection against corrosion reaches broad indicators due to their obvious advantages: simplicity of preparation, low cost, environmental friendliness, and a long period of resistance to the effects of an aggressive environment on the coating. Sulfuric electrolytes of galvanizing containing a complex of SAS used in combination with each other were investigated. Their effective influence on the protective properties and appearance of zinc coatings is shown. The qualitative and quantitative composition of zinc coatings on a JSM-6490LV raster electron microscope with the systems of energy dispersive microanalysis of INSAEnergu and HKL - Basicc structural analysis with a useful magnification of 300,000 was investigated. Obtained non-porous, fine-crystalline, dense, bright galvanic zinc coatings from electrolytes with surfactants with good adhesion to the base, a comparison of their quality is given, conclusions are made.
