摘要 |
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. |
