Enhanced Mass Transport In Electrogalvanizing Systems By Hydrogen Evolution
The effect of hydrogen evolution on mass transport during electrogalvanizing was evaluated for a vertical electrode by using a electrochemical tracer. The potentiodynamically measured limiting current of a cadmium tracer was compared with those obtained by the codeposition method at various current densities. The effects of pH on the hydrogen evolution and the mass transfer rate during electrogalvanizing were also determined. The Sherwood number was calculated and compared with that predicted by natural convection. It has been found that the mass transport was mainly enhanced by natural convection at current densities less than 25 mA cm-2 and by simultaneous hydrogen evolution at relatively higher current densities. © 1988.
