Abstract
A process and device for galvanic deposition of a dispersion coating on the cylindrical or slightly conical inner face of a cathode workpiece effect the continuous feed of a circulating electrolyte containing metal ions and suspended, fine-grained hard particles. The cathodically polarized workpiece or its inner face is employed at least as the upper part of the outer wall of the ring-shaped electrolyte container. This inner face is fed electrolyte in the form of a rising, spiral-shaped but vortex-free stream. The process is employed for all cylindrical or slightly conical metallic inner faces which are at least open on one side, in particular for coating brake drums made of aluminum or an aluminum alloy.
