In the interest of decreasing the amount of chromium and other electrolytic effluents that enter the waste stream during chromium electrodeposition processes, and of optimizing plating speeds at reduced chromic acid concentrations, the authors seek to establish the effects of decreasing the chromic acid concentration in the electrolyte on the microstructure, microhardness, internal stress behavior, and tendency toward hydridation of chromium coatings obtained from various electrolyte compositions. Plating kinetics and lattice parameters were also investigated.
