Abstract:
1. A process for electrochemically coating a substrate by brush plating, comprising: supplying an electrolyte, in which particles are dispersed, to a carrier, the electrolyte and the particles being supplied to the carrier by a process comprising: supplying the electrolyte to the carrier via a first conduit system, in which the concentration of particles is at least reduced compared to a required concentration of particles for the coating, or no particles are present; and supplying particles to the carrier via a second conduit system fluidically independent from the first conduit system, the second conduit system adding particles to the electrolyte until the required concentration of particles is achieved therein; using capillary channels in the carrier to guide the electrolyte, in which particles are dispersed, from the first and second conduit systems, to thereby form a dispersion on the substrate; and electrochemically forming a metallic layer from the electrolyte, in which particles are dispersed, the metallic layer having a matrix in which the particles are incorporated; wherein the carrier is a brush.
