ABSTRACT:
The present invention relates to an electromagnetic system for applying a coating to a metal or metal alloy substrate. The system utilizes a high frequency electromagnetic field to maintain a supply of coating material in a molten condition, to restrict the flow of the molten coating material, and to control the thickness of the applied coating layer. Downstream cooling solidifies the coating layer. The system has particular utility in forming tin coated copper or copper base alloy products.
