摘要：Mining machines are prone to be corroded because of their terrible working conditions. Zinc-plating can enhance the corrosion resistance of workpiece of mining machine. The traditional mechanical plating process is not suitable for parts of big bulk and of complex surface. In order to overcome above shortcoming of mechanical plating, a novel wet ultrasonic mechanical plating process was present by integrating the theories of mechanical plating and ultrasonic shot peen. Wet ultrasonic mechanical plating equipment which includes the ultrasonic generator, ultrasonic transducer and amplitude transformer horn was designed. Galvanized tests were carried out using the equipment. The thickness of plating layer was measured using coating thickness gauge. The bonding strength between the coating and substrate were studied by grid test．The results show that plating layer whose maximum thickness can reach 30 μm can be gotten on the surface of workpiece using this equipment. The bonding strength between the coating and substrate is satisfactory.
