| Abstract Scope |
In the work, zinc coatings were obtained using a technology using complex functionally active mixtures. The tests were carried out in acid solutions and 3% NaCl solution, which imitated the use of table salt to remove ice from roads in winter. The study was carried out on samples of galvanized steel A622 and A620 using a pH meter. The stationary potential was established after 90–180 min. after the start of the experience. In order to increase the corrosion resistance of sheet steel used in the automotive industry, zinc coatings were alloyed with aluminum at temperatures of 520-570 ° C. During galvanizing, δ1, G, Fe2Al5 and FeAl3 phases are formed, and during hot galvanizing, α-phase, G-phase with content of 25-27% Fe, δ1 and FeZn13. |
