Cathodic polarization curves of lead, cadmium and lead| cadmium fluorosilicate baths were studied.
The action of the combined brightener was studied by Hull Cell test, the determination of cathodic current efficiency and polarization curves.
Its property of electrochemical catalyzed hydrogen evolution has been studied by means of cathodic polarization curves, A. C. impedance technique, and its surface morphology was observed with SEM.
The effects of annealing on the activity of al alloy anode were studied by measurement of polarization curves and analysis of SEM.
