This study improvements, such as main salt , complexing agents , buffering agents, a conductive salt , the choice of additives , and each component optimum ratio of the trivalent chromium plating solution component . In the anode material , an insoluble anode performance of the titanium-based oxide coating , so that the anode does not produce or less produce Cr 6 ion , thereby avoiding the contamination of the anode bath , to ensure that the production can be continuously long stably performed. By controlling the pH, temperature , current density, plating time , and other process conditions , the cathode coating to improve the corrosion resistance, hardness , impact resistance. The design of the bath and its electroplating process , to speed up the solution circulation , better buffer and suitable complexing agents and additives to increase the concentration of the complexing agent to increase the stability of the complexation reactions , suitable anode the material ideal electroplating way measures. The obtained coating and traditional hexavalent chromium compare unique advantages .
