Abstract (en)

[origin: DE19537657A1] The description relates to a process for making a contact with a basic body of good electrically conductive material (first material) and a contact layer of less electrically conductive material (second material) which is resistant to arc burning, in which the contact layer has a sintered structure soaked with the material of the basic body. The basic body and the sintered structure are applied one on the other in a cup-like mould, heated therein to above the melting point of the first material but still below that of the second, so that the first material melts and penetrates the sintered structure. Here the sintered structure can be produced by scattering the second material in powder form on the first and first sintering in a degassing process below the melting point of the first material. It is also possible to produce the sintered structure beforehand and lay a green compact on the basic body.
