摘要： Balls of silver alloy are internally oxidized and used for the production of electric contacts. The electric contacts produced by using the above internally oxidized balls have much better electric properties than those which are produced by using internally oxidized plate or wire of silver alloy. Further, the above internally oxidized balls have higher ductility than those which are produced by using internally oxidized plate or wire. Composite electric contacts of internally oxidized silver alloy and base metal produced by a cold welding process contain an increased amount of solute-metal by the use of the abovedescribed internally oxidized balls.

摘要： A CONTACT METAL HAVING GOOD COLD-PRESSURE BONDING PROPERTIES IS BONDED TO A METAL SUBSTRATE WHICH NORMALLY HAS A LOW PROPENSITY FOR COLD-PRESSURE BONDING. THE CONTACT METAL, E.G. SILVER, IS PLACED ON THE METAL SUBSTRATE, SUCH AS STAINLESS STEEL, AND THE CONTACT METAL IMMEDIATELY COLD DEFORMED BY CONTACT WITH A PUNCH UNTIL A BALANCE IS ACHIEVED BETWEEN THE APPLIED PRESSURE AND THE DEFORMATION RESISTANCE OF THE CONTACT METAL, WHEREBY THE CONTACT METAL IS BROUGHT INTO INTIMATE CRYSTALLOGRAPHIC CONTACT WITH THE SUBSTRATE. IMMEDIATELY THEREAFTER, WHILE THE CONTACT METAL IS STILL UNDER PRESSURE, THE CONTACT METAL IS HEATED TO ABOVE ITS RECRYSTALLIZATION TEMPERATURE AND BELOW ITS MELTING POINT TO COMPLETE THE DEFORMATION OF SAID METAL AND EFFECT METALLURGICAL BONDING TO THE SUBSTRATE.

摘要： A RIVET-TYPE BIMETAL CONTACT IS PRODUCED BY COAXIALLY SUPERPOSING A LINEAR PIECE OF A DUCTILE PRECIOUS CONTACT METAL ONTO THE END FACE OF A DIFFERENT DUCTILE METAL WITH ITS OPPOSITE END ANCHORED IN A DIE, THE CONTACT FACES OF THE TWO METALS BEING FRESHLY CUT. THE CONTACT METAL IS AXIALLY UPSET BY APPLYING IMPACT PRESSURE TO DEFORM AND FLATTEN THE SUPERPOSED METALS AT LEAST 20% OF THEIR HEIGHT, AND PREFERABLY AT LEAST 30 OR 50%, TO BRING THE CUT FACES INTO INTIMATE AND CRYSTALLOGRAPHIC CONTACT WHEREBY THE INTERFACE IS INCREASED IN AREA AND EFFECT COLD BONDING OF THE TWO FACES, AND THEN IMMEDIATELY HEATING THE TWO METALS TO AN ELEVATED TEMPERATURE BELOW THE MELTING POINTS
OF THE METALS BUT ABOVE THE RECRYSTALLIZATION TEMPERATURE WHILE UNDER PRESSURE TO COMPLETE THE DEFORMATION AND FORM A HIGH STRENGTH BOND AT THE BIMETAL INTERFACE.-

摘要： A method and apparatus are provided for pressure-bonding a precious contact metal selected from the group consisting of silver, platinum, gold, palladium and alloys based on these metals to a metal substrate strip selected from the group consisting of copper, nickel, copper-base and nickel-base alloys to which the contact metal is cold bondable. The invention includes feeding a strip of the metal substrate towards a bonding station comprising upper and lower dies, one die being adapted to apply pressure to the other, producing a freshly cut or fractured surface in a portion of the strip before it reaches the bonding station, freshly cutting or fracturing the piece of precious contact metal, superposing the precious metal against the substrate with their freshly fractured surfaces in contact with each other, and then immediately applying impact pressure to the superposed metal portions by means of the pressure-applying die sufficient to deform the precious metal at least 30 percent of its thickness against the substrate whereby to cold bond the precious metal to the substrate. Precious metal cladded to a base metal of copper, nickel, copper-base and nickel-base alloys may be used as contact metal, the cladded precious metal being freshly fractured through the base metal side for bonding to the metal substrate strip.
