use of a binary or ternary copper lead tin alloy for gleitschichten

摘要

A multi-layered plain slide bearing having a metal base layer, and having a slide layer which is carried by the base layer and which comprises a copper-lead-tin binary or ternary alloy that has been applied to the base layer and that has an unusually high cooper content. The slide layer can contain, by weight, from 20% to 70% of copper, at least 15% and at the most 80% of lead, and from 0% to 30% of tin, and can also optionally contain indium, cadmium or other like metals. The slide bearing can further include a run-in layer which covers the slide layer, and which contains copper, tin, indium and/or lead or their oxides, sulfides or phosphides.
