Surface coating processing the workpiece through an anode-cathode reaction in a salty solution is coated with a thin and ductile layers of zinc. Beskrivning The process Before processing can begin the work should have been pre-treated to achieve a clean surface, common practice is by electrolytic cleaning followed by pickling and rinsing. The workpiece that acts as a cathode and the surface coating agent who acts as the anode is connected to a power source and immersed in a saline solution. The zinc ions are released from the anode, creating a zinc coating on the cathode. The process is ideal for implementing continuous coating of wire and coils. Electro-galvanization
