Embodiment Construction

[0027] On prefabricated bearings made of a composite of steel and a bearing alloy of CuPb22Sn, after appropriate pretreatment, a nickel diffusion barrier is applied from Watt's nickel electrolyte.

[0028] A bismuth-based sliding layer is deposited galvanically on the nickel intermediate layer produced in this way. The following water-based electrolyte systems are used here:

[0029] Bi 3+ As bismuth methanesulfonate 30-40g / l

[0030] Cu 2+ As copper methanesulfonate 1-5g / l

[0031] Ag + As silver methanesulfonate 0.1-2g / l

[0032] Methanesulfonic acid 150-200g / l

[0033] Additive "N" (Cerolyt BMM-T) 50-70g / 1

[0034] Additive "L" (Cerolyt BMM-T) 10-20g / l

[0035]Resorcinol 2-3g / l

[0036] Thiourea 30-150g / l

[0037] Thiourea should not be used when silver methanesulfonate is not used.

[0038] Bismuth is used as the anode material. The temperature of the tank used to deposit the sliding layer is 15-40°C. Use 1.5-4 x 10 -2 A / m 2 the current density. The anode-t...

Abstract

The invention is a method for the production of a composite multilayer material having a backing layer, a bearing metal layer of a copper alloy or an aluminum alloy, a nickel intermediate layer and an overlay consisting of about 0-20 wt. % copper and about 0-20 wt. % silver, the combined maximum wt. % of copper and silver being about 20 wt. %, the rest being bismuth, and the layer thickness of the nickel layer amounts to more than 4 mum by electrodeposition, in which the overlay is deposited from methyl sulphonic acid-based electrolyte.

Description

technical field [0001] The invention relates to a laminated composite material, in particular for plain bearings or bushings, having a carrier layer, a bearing alloy layer made of copper alloy or aluminum alloy, a nickel intermediate layer and a sliding layer. Furthermore, the invention relates to a method for producing such a layered composite material, to the production of plain bearings or bushings and to the use of the layered composite material. Background technique [0002] A classical layered composite with a structure of a steel back as carrier layer, lead bronze as bearing alloy layer and a sliding layer of lead-tin-copper, as described in Glyco-Ingenieurberichte 1 / 91, by its height Proved to be superior in terms of reliability and mechanical load carrying capacity. The sliding layer is deposited galvanically here. Here it is a multifunctional layer into which foreign particles can be embedded, which serves as a corrosion protection layer, which exhibits emergency...
