The invention relates to a tool for galvanically coating sliding bearings comprising at least one cover, to which a thief is attached.

Tool for galvanically coating sliding bearings

A composite multilayer material is described, which exhibits a relatively high specific load carrying capacity and relatively low wear. The composite multilayer material for plain bearings comprises a backing layer, a bearing metallayer ( ), a first intermediate layer ( ) of nickel, a second intermediate layer ( ) of tin and nickel together with an overlay ( ) consisting of copper and tin. The overlay ( ) comprises a tin matrix ( ), into which tin-copper particles ( ) are incorporated, which consist of 39 to 55 wt. % copper, the rest being tin. At high temperatures, as occur in the case of plain bearings used in internal combustion engines, the tin migrates into the second intermediate layer ( ) therebelow, resulting in concentration of the tin-copper particles ( ).

Composite multilayer material for plain bearings

A lead-free multilayer material for plain bearings and a process for the production of corresponding bearing shells for improved emergency running and mechanical load-carrying capacity characteristics. The multilayer bearing material comprises a lead-free copper alloy having a copper content ranging from 50 to 95 wt. %, and an overlay formed of a lead-free tin and copper having a tin content ranging from 70 to 97 wt. % and a copper content ranging from 3 to 20 wt. %.

Overlay material for plain bearing

Method of fabricating plain bearings

A composite material for plain bearings comprises a backing layer, a bearing metal layer consisting of a copper alloy with a copper content of from 50 to 95 wt. % or an aluminum alloy with an aluminum content of from 60 to 95 wt. %, a diffusion barrier layer and an overlay, applied by electroplating, consisting of a lead-free, tin and copper-containing alloy. The invention provides a composite multilayer material whose overlay, applied by electroplating, does not exhibit any embrittlement even at relatively high temperatures, irrespective of the copper content. The overlay preferably comprises from 8 to 30 wt. % copper, 60 to 97 wt. % tin and 0.5-19 wt. % cobalt.

Composite multilayer bearing material

A multilayer material is described, whose overlay exhibits improved hardness and improved wear-resistance. The multilayer material includes an overlay, which contains 8-18.5 wt. % tin and 2-16 wt. % copper, the balance being lead, wherein the tin is present as a finely crystalline deposit completely homogeneously distributed in the lead. A process for producing sliding elements in which the overlay of lead-tin-copper is applied to the prefabricated semi-finished product by electroplating provides that a ternary, fluoroborate-free electroplating bath is used without brighteners and with the addition of fatty acid polyglycol ester and a grain refining agent including a carboxylic acid.
