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.

Abstract: A body of a soft metal, such as gold, silver, or copper, is ultrasonically bonded to another metal body by providing a thin layer of a harder material, such as nickel, iron, cobalt, magnesium, aluminum, palladium, germanium, or silicon, between the surface of the soft metal body and the other metal body. The layer of the harder material is thin enough that it is worn away during the application of the ultrasonic energy so as to provide the bond directly between the soft metal body and the other body.

Abstract translation: 通过提供诸如镍，铁，钴，镁，铝，钯，锗或更多的较硬材料的薄层，将诸如金，银或铜的软金属体整体结合到另一金属体上 硅，在软金属体的表面和另一金属体之间。 较硬的材料层足够薄，使其在施加超声波能量期间被磨损，以便在软金属体和另一体之间直接提供粘结。
