Schichtverbundwerkstoff für Gleitelemente und Verfahren zu seiner Herstellung

摘要

Disclosed is a method for producing stratified composite materials that exhibit optimum properties during their entire service life. The stratified composite material has a carrier layer, a bearing metal layer, an intermediate layer and an electroplated sliding layer that continually increases in hardness from the surface thereof in the direction of the bearing metal layer. According to the inventive method, a lead-free alloy with at least one hard component and one soft component is electrodeposited, whereby the current density is modified within a range of 0.3 20 A/dm<2> during the deposition process and/or the temperature of the galvanic bath is modified within a range of 15 DEG C - 80 DEG C.
