Abstract: A process for the electrolytic deposition of chromium by means of a bath of trivalent chromium is characterized in that it uses, as electrolyte, a solution which is obtained by careful reduction of the chromic acid in a sulfuric medium by an excess of a reducing agent of the alcohol type, such as methanol. Subsequently this solution is diluted with water without indispensable addition of additional products. The electrolysis is effected without separation of the anodic and cathodic compartments at an anode-cathode potential difference greater than 6 volts, the cathodic current density being of the order of 10 to 40 amperes per dm.sup.2, the concentration of trivalent chromium ranging from 0,1 to 1 ion-gram per liter and the pH from 1 to 1,5.
