ABSTRACT:
This invention relates to a method of electroforming the epitrochoidal running track for the rotor of a rotary internal combustion engine. The method involves the electrodeposition of a sequence of plates on a mandrel of epitrochoidal shape and having a chromium surface, and casting an aluminum alloy housing onto the final plate. The sequence of plates applied to the mandrel with the chromium surface involving (1) a first plate of poor adherence selected from the group consisting essentially of nickel, cobalt, iron or their alloys, (2) a wear-resistant plate and (3) a final plate to aid in securing good adhesion of the aluminum housing cast thereon. These are the main steps. Intermediate steps may also be involved such as using two or more wear-resistant plates in step (2). Also step (1) with step (2) can be combined in one plating step.
