Abstract
The invention relates to a process for producing a sliding body made up of a base body and a slide plate with a running surface arranged on the base body, wherein the slide plate and the base body are joined to one another by capacitor discharge welding. It is preferable for sliding bodies of this type to be used as a sliding shoe for hydrostatic piston engines. The running surface of the slide plate is made of a nonferrous-metal sliding bearing material produced by spray-compacting and, in particular, is made of a copper-tin-titanium alloy produced by spray-compacting and contains 13.5 to 20% by weight of tin, 0.05 to 0.5% by weight of titanium, remainder copper and optionally one or more of the elements selected from silicon, chromium and zirconium up to a total amount of 1.0% by weight, plus inevitable impurities.
