THE DEVELOPMENT OF ELECTROFORMING TECHNIQUES.
Abstract
A test program was initiated to define objectives and further develop electroforming techniques investigated under Test Request 513-277. Mandrel materials selected for evaluation were polystyrene, plexiglass (lucite), cerrotru, polyurethane and renwood. Nickel was electrodeposited from a sulfamate electroplating bath on the prepared mandrels to the desired thickness. Completed electroformed parts were separated from their mandrels utilizing appropriate techniques. Parts successfully electroformed included a wave guide, a bellows and a pitot tube. A sandwich structure attempted was not completed. A study form of renwood was designed and electroformed to evaluate the deposition of nickel on inuside and outside corners as well as in blind holes. The internal stress produced by the nickel sulfamate bath was determined with the aid of the BrennerSenderoff Contractometer. In view of the initiation of a more extensive electroforming Test Rrquest (TR E9661-060) work on this Test Request was suspended, even though incomplete, and efforts were directed to the more extensive request.
