Title:
電気接点用半完成品の製造方法、及び、電気接点用半完成品、及び、電気接点部材
Document Type and Number:
Japanese Patent JP5559183
Kind Code:
B2
Abstract:
The method relates to a method for producing a strand-like, particularly band-like semi-finished part for electrical contacts, wherein the semi-finished part has a top side intended for making the electrical contact, said top side made from a silver-based composite material in which one or multiple metal oxides or carbon are embedded, and has a carrier layer supporting the composite material made of easily solderable or weldable ignoble metal, and method having the following steps: Powder-metallurgic production of a block made from the silver-based composite material, encasing of the block made of the composite material with a powder made from the easily solderable or weldable ignoble metal, compressing the block, encased by the metal powder, to condense the metal powder, sintering the compressed block in a reducing atmosphere or in an inert atmosphere or in a vacuum, avoiding the formation of fluid eutectics from the silver of the composite material and from the non-precious metal with which the block made from the silver-based composite material is encased, reshaping of the sintered block by extrusion pressing, creating a partial strand with a top side made from composite material and a bottom side made from non-precious metal.
