The throwing and covering power, as well as corrosivity, of highly concentrated chrome-plating electrolytes containing chloride are studied. It is found that the throwing and covering powers of these electrolytes are somewhat higher than those of common electrolyte and improve with an increase and a decrease in the concentration of chromic anhydride and chloride, respectively. The electrolyte corrosivity for steel decreases with an increase in the chromic acid concentration due most probably to an increase in its passivating action.
