The passivation of cadmium and cadmium amalgam in alkaline solutions has been studied by the galvanostatic transient technique. The dependence of ir w on i at low current densities and constancy at high current densities observed fits well with the theoretical relationship derived by Reddy, Devanath
The anodic dissolution and passivation of vertical porous zinc electrodes that were prepared by pressing zinc powder or amalgamated zinc powder into small disks were studied in 6 M KOH + O-25 M ZnO by measuring potentiostatic current/potential curves at a rate of 1 mV/s and by taking photomicrograph
As a preliminary stage in the study of the active~passive transition on zinc in concentrated (6.8 mol dm-3) solutions of KOH the reported mechanisms have been reviewed and the characteristics of active dissolution prior to passivation have been investigated. The theory of Armstrong and Bulman has be
