Abstract

A systematic study of the electroplating of bright cadmium from an acetate bath is described. The process was carried out in electrolytes containing cadmium acetate with inclusion of boric acid, acetic acid and sodium acetate, in addition to gelatin and toluene-4-sulphonic acid as organic additives. The effects of the bath constituents on the cathodic polarization and the current efficiency of cadmium deposition from each bath as well as on the surface morphology of the as-formed cadmium electroplates is discussed. The optimum acetate bath composition is suggested. The influence of a superimposed sinusoidal a.c. with the d.c. on the above-mentioned characteristics of cadmium electroplating from the optimum bath was also examined.
