Abstract

A laminated material for sliding members having improved resistance to abrasion, hardness and wear resistance. The laminated material has a support structure and a sliding layer with electrodeposited matrix material, hard particles being embedded into the matrix material, having a diameter of <2 .mu.m and being provided in the form of individual particles distributed in a completely homogenous manner with a proportion of 2 to 20% by volume in the matrix material. The process to produce sliding members provides that a ternary electroplating bath free of fluoro-borate and without brighteners, using non-ionic surfactants and free alkyl sulphonic acids, and a grain refining agent and a fatty acid polyglycol ester is used. The hard particles are kept in the electroplating bath during electroplating at a steady concentration.
