Immersion tin coatings were formed directly on aluminium by microwave irradiation from acidic tin chloride bath. The corrosion resistance behaviour of the coatings was studied by Tafel polarization and EIS. The effects of bath composition, temperature and irradiation time on the kinetics of immersion plating of tin onto aluminium were investigated. The surface morphology of the coatings has been analyzed by SEM. The phase composition of the coatings was analyzed by X-Ray Diffraction. The deposit structure is found to be more crystalline. It is found that the deposited tin is dissolved again after a long time immersion in plating solution.
