Abstract:
A method of producing a contact element, which comprises:providing a base body made of a first material having a good electrical conductivity and having a first melting temperature;providing a contact layer made of a second material having an electrical conductivity less than the electrical conductivity of the base body, having a sinter structure, being resistant to arc erosion and having a second melting temperature;placing the base body and the sinter structure one above the other in a cup-like mold; andheating the base body and the sinter structure in the mold to a temperature above the first melting temperature but below the second melting temperature, for fusing, penetrating and impregnating only a portion of the first material into the sinter structure to produce a contact element having a layer made from the base body and another layer made from the contact layer.
