Method for Anodising the Metallic Inner Surfaces of a Capillar Cavity

Dr. Fichtner, Dr. Schubert, Dr. Wunsch


The aim of the invention is to anodise the metallic surfaces of a capillar cavity. To achieve this, an electrolyte flows through the cavity, the inner surfaces are connected to the anode of a voltage source and an electrode, which is connected to the cathode of the voltage source, is immersed in the electrolyte that lies outside the cavity.
