    摘要: The present invention is a rivet contact including a head portion and a foot portion having a smaller width than the head portion, wherein the head portion contains a contact material layer having at least a top containing an Ag-based contact material; the rest of the head portion and the foot portion contain a base material containing Cu or a Cu alloy; and a barrier layer including an Ag alloy is provided at a junction interface between the contact material and the base material. Here, an Ag alloy obtained in such a manner that one or more base metal elements of Sn, In, Cu, Ni, Fe, Co, W, Mo, Zn, Cd, Te, and Bi are added to Ag by 0.03 to 20 mass % is preferably used as the Ag alloy constituting the barrier layer.

    摘要: Internal oxidized Ag-SnO system alloy electrical contact materials having a moderate initial contact resistance and having no depletion layer is disclosed. The alloy is internal oxidized by having it sandwiched between pure silver thin layers, and is cut horizontally right in two, simultaneously removing the depletion layer from the internally oxidized alloy.

    摘要: A method of making silver-cadmium oxide-tin oxide type contact materials by oxidizing three-dimensional particles containing silver, cadmium, and tin and then consolidating the oxidized particles into bodies of the desired configuration. The resultant contact materials have a substantially uniform distribution of relatively coarse cadmium oxide particles, improved arc erosion properties, and little or no depleted or porous grain boundaries.

    摘要: To make an electric contact material, a molten alloy of silver and a non-noble metal is atomized into spheroidal particles having a particle size ranging up to almost 1 mm, and the fraction of these particles having a particle size ranging between 0.2 and 1 mm is separated, a small remainder of smaller particle size being treated as a reflux. This fraction is heated in an oxidizing atmosphere to oxidize the non-noble metal internally within the particles and the latter are then mechanically broken, as by suitable milling or pulverizing, into fragments having a particle size no greater than about 0.3 mm. The fragmented particles are then compressed, as by pressure molding, extrusion, etc., and sintered to provide a sintered silver-metal oxide electric contact material.
