| This article describes the study of corrosion resistance of tin coatings deposited onto aluminum alloy substrates using the low pressure cold spraying and electroplating methods. The chemical corrosion resistance was examined using the Kesternich and cyclic salt spray tests inside SO2 and NaCl climate chambers, respectively. The selected tests allowed simulation of the conditions of the coatings during service. The results were satisfactory for low pressure cold spraying coatings. Coatings produced by electroplating exhibit substantial corrosive losses due to their method of application and low thickness. Evaluation of corrosion were carried out by analyzing changes in the microstructure. Additionally, the physicochemical tests were carried out using X-ray diffraction to verify corrosion changes on the coatings surface. |
