Lead-free cufe2p-plain bearing material with cutting agent

Abstract

The invention relates to a plain bearing material having a matrix material comprising 2.1-2.6% by weight of iron, 0.05-0.2% by weight of zinc, 0.015-0.15% by weight of phosphorus, ≤0.03% by weight of lead, ≤0.2 % by weight of molten metallurgical related impurities and balance copper, optionally with at least one hard material and optionally with at least one solid lubricating material, and with at least one selected from the group consisting of tellurium, sulfur, chromium and Zirconium additive. Furthermore, the invention relates to a plain bearing composite having a carrier layer, a bearing metal layer and a sliding layer applied on the bearing metal layer, wherein the bearing metal layer consists of such a plain bearing material, and the plain bearing comprises such a Sliding elements or plain bearings made of composite materials.

Description

technical field [0001] The invention relates to a sliding bearing material, which has a base material, the base material is composed of 2.1-2.6 wt. % iron, 0.05-0.2 wt. % zinc, 0.015-0.15 wt. % phosphorus, ≤0.03 wt. % lead, ≤0.2 wt. % The melt consists of metallurgically relevant impurities in wt. % and the balance in copper. Furthermore, the invention relates to a plain bearing composite having a carrier layer, a bearing metal layer and a sliding layer applied on the bearing metal layer, as well as a sliding element, in particular a radial plain bearing in the form of a bushing or a bearing sleeve. Background technique [0002] Lead-free copper-iron-phosphorus-based materials, later also called CuFe2P-alloys, have long been generally known and have also been used for some time as plain bearing materials, in particular as sliding bearings for bushings or bearing sleeves. Bearing composites are used. See, for example, the documents DE 10 2009 002 894 A1 and DE 10 2011 00736...
