Method for producing multi-layer sliding contacts, and sliding contacts obtained by means of the method

摘要

The method, which includes loading a mould (3) with at least one electrically conductive powder (4), compression of the contents of the mould with the aid of a piston (5) in order to form a bare sliding contact (7), heat treatment of the bare sliding contact (7) and attachment of the ends of the electrical conductors (2), is characterised in that the loading includes at least one simultaneous insertion of at least two conductive powders (4B, 4A and/or 4C...) in such a manner that a sliding contact is obtained which is formed from firmly bonded blocks (1B, 1A and/1C...), the boundary surface (1AB and/or 1BC...) between these blocks being aligned at least partially along the compression direction (13). Multilayer sliding contacts obtained in accordance with this method. IMAGE
