ABSTRACT:
A method of making a laminated structure for use in an electrical apparatus. A female mold is produced having an upwardly facing cavity of a shape corresponding to the laminated structure. A layer of a ferrous metal is sprayed onto the bottom surface of the mold and subsequently an electrically insulated layer is applied to the layer of metal. Alternate layers of the ferrous metal and the insulating layer are deposited in the cavity of the mold to provide a laminated structure in which the metal and insulating layers are integrally bonded together. Through use of the method of the invention, a ferrous metal with the most desirable electrical characteristics can be employed.
