Dispersion electrolyte for graphite particle-containing tin-nickel alloy layers

Abstract

The invention relates to a dispersion electrolyte for the electrodeposition of graphite particle-containing tin-nickel alloy layers on a metal or metalized substrate. The dispersion electrolyte contains Sn2+ ions, Ni2+ ions, graphite particles, at least one dispersant selected from anionic and nonionic dispersants, ions of at least one third alloying element and / or at least one further organic compound which is decomposed during the electrodeposition and serves as a source of carbon as a third alloying element, and water. The dispersion electrolyte has a pH of
