Chromium metal deposition general way the market is almost as plating layer, and its technology and to explore a variety of more sophisticated questions, but domestic chrome plating for non-related research rarely, and even non-related chemical composition of plating bath studies, while the chromium-free plating study the deposition of very low efficiency. In this study, combined electric plating and chemical-free way composite deposition coating of chromium metal plate attached to on, and to achieve good deposition rate and luster, mainly for the combination of electroless plating and ultrasonic technology combined with a vibration-assisted deposition of Cr layer on the substrate , the use of stainless steel and copper as the substrate, respectively, Pb-Sn alloy and pure tin metal as the anode, and chromic acid solution in order to add additional agents as the solution to conduct electricity without electroplating and chemical deposition of composite processing, the proposed method can be used purely to improve the electroplating and electroless plating of disadvantage and enhance the current efficiency, deposition rate and surface gloss.
