Abstract
Plated memory wire is provided with a nickel-phosphorous alloy protective coating through an electro-deposition process. The protective coating is electrically conductive, nonmagnetic and has a bright surface amenable to good solder bonding. The memory function is provided by a Saccharin-type nickel-iron-cobalt film and the protective overcoating is applied by submerging the wire in an electrolyte bath composed of 360 g/l of nickel sulfate (NiSO.sub.4.6H.sub.2 O), 80 g/l of sodium sulfate (Na.sub.2 SO.sub.4), 60 g/l of sodium hypophosphite (NaH.sub.2 PO.sub.2.H.sub.2 O) and 25 g/l of boric acid (H.sub.3 BO.sub.3). The static bath is maintained at room temperature and the wire is moved through it at approximately eighteen inches per minute. An electro-deposition current density of from 20 to 80 ma./cm..sup.2 of plating area is employed.
