Passivation of spec-pure Sn was studied in aerated, unstirred solutions of acid sulphate (H2S04/Na2S04) and neutral suphate (Na2S04) using the potentiodynamic technique from an initial cathodic potential (-ve to open circuit potential) in the anodic direction and backwards to the initial potential.
The influence of Sn on the formation of the corrosion layer on Pb has been studied with a Pb-lO%Sn electrode in 0.5 and 4.5 M sulphuric acid using voltammetry, rrde and potential decay measurements, as well as photoelectrochemistry and ac impedance. The results obtained support the conclusion that i
Galvanostatic cyclic anodic and cathodic polarization curves of seven copper-tin alloys were traced on O-01, O-1 and 2N NaOH solutions at 25". The tin content of the alloys was varied between 8 and 76 wt-%. The results obtained are explained in relation to the phase diagram of the copper-tin system.
