ABSTRACT:
Process suitable for providing a substrate with a protective coating based on chromium, including a chromium matrix in which solid particles are distributed. The process includes a step of electrodeposition of the coating carried out by passing an electric current between a cathode or cathodes of the substrate to be coated and an anode or anodes. The cathode(s) and anode(s) are immersed in an electroplating solution, wherein the electroplating solution is based on an aqueous solution including trivalent chromium obtained from the reduction of chromic acid by a reducing agent, and contains solid particles.
