anticorrosive properties -- electroplating -- surfactants -- thiourea derivatives
Аннотация: For a long time, the use of various surfactants in the composition of simple electrolytes by researchers to improve the quality of metal coatings with cadmium and zinc has been an urgent task.Surfactants contribute to the grinding of the coating structure, the elimination of their porosity and the appearance of anti-corrosion properties of coatings. For example, cadmium electroplated coatings require corrosion resistance, since they are operated in tropical climates, in underground tunnels. Zinc coatings are widely used in building structures and roofing, on electrified railways and high-voltage power lines, in the mining industry and water pipes, as well as for galvanizing the body material in modern all-terrain vehicles to pass in hard-to-reach places without being subjected to corrosion.The object of our research is the process of electrodeposition of cadmium and zinc from simple acidic electrolytes with surfactants, which are thiourea derivatives of dialkyl-phosphorous acids in the current density range of 0.5-3.5 A /dm2, at room temperature. To confirm the quality of the obtained electroplating, we used a JSM-6490LV scanning electron microscope with INSA Energu energy–dispersion microanalysis and HKL-Basicc structural analysis systems with a useful magnification of 300000.
