Abstract: A wire of a soft metal, such as gold, silver, or copper, can be ultrasonically bonded to a base metal substrate by coating the wire with a thin layer of an alloy of nickel-phosphorus, coating the substrate with a relatively thicker layer of an alloy of cobalt-phosphorus, and applying ultrasonic vibratory energy between the coated wire and the coated substrate. A portion of the thin layer of the nickel-phosphorus is worn away during the application of the ultrasonic vibratory energy, and the wire is bonded directly to the relatively thicker layer of cobaltphosphorus.
