Abstract
In order to produce differently thick dispersion layers on inner surfaces of hollow bodies, it is proposed according to the present invention to permit electrolyte to flow into the hollow body by way of a swirl-producing flow body, whereby the flow is split up into a laminar and a turbulent component. With turbulent flow, a high build-up rate of the solid particles is achieved than with laminar flow so that layes of different concentration can be realized in a single operation.
