Copper dip plating of iron and steel is being paid attention to all along , and the study on it is still conducted continuously. Dip plating is a displacement plating in substance. If a copper coating with good adhesion to the substrate of iron and steel obtained after dip plating is wanted, the substrate surface must be very clean, the speed of displacement plating must be low considerably, and thickness of the displacement coating must be thin relatively. How to lower down the displacement speed becomes a key to the copper dip plating technolgy. It was found from the test results that for lowering down the copper displacement speed the employments of inhibitor and coordination agent have their advantages and disadvantages respectively, and the employment of copper-iron electric couple has a certain effect, How to ensure the realization of highly cleanliness of the workpiece surface and the practicability of materials with low purity in mass production are the controll factors for realizing industrial application of copper dip plating technology for iron and steel articles.
