Abstract
A method of forming articles on an electrically conductive mandrel, and the article produced, is disclosed. Initially, a first layer of metal is electroformed on the mandrel; then alternating electrolessly deposited metal layers of, e.g., two different metals are deposited on the electroformed first layer to form a bi-metallic laminated structure; and then a final layer of metal is electroformed on the laminated structure. The mandrel is then removed to form the article. This method provides a more uniform wall thickness of the final article, even when the mandrel has inner wall portions (e.g., grooves, slots, holes, etc.), as compared with articles formed by conventional electroforming techniques. This method can be used, among other uses, to form corrugated waveguide horns for extremely high frequency applications.
