Influence of anionic composition during electrodeposition of cadmium from cadmium trilonate electrolyte

The studies have been conducted to indicate that out of sulfate, chloride, nitrate and hydroxide trilonate electrolytes of cadmium plating consisting (kg/m3): cadmium salt (in conversion to metal) - 31-35, trilon B-120-130, pH 6.5-7.5, cadmium chloride and cadmium sulfate electrolytes are the best ones. They possess high technological parameters (the quality of cathode deposition, the yield in current, disperbility). Comparison of protective properties of coatings of these electrolytes has shown that coatings of chloride electrolytes are less porous and more corrosion resistant
