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.

The heat-resistance of coating from deposited steel 15N8G6M3FTB at temperature of 900 °С is studied. It is established that this dependence occurs in the first hours. The average mass gain of the metal scale of such coating at 900 °С is 0.0128 kg/(m2 •h). It is shown that the basis of metal scale of the composition 15N8G6M3FTB is hematite Fe2O3 and magnetite Fe3O4, as well as MnO, which have protective properties. The number of other phase compounds with high protective properties is negligible. The coating from steel 15N8G6M3FTB can be used for applying to the surface of parts operating at elevated temperatures.
