ABSTRACT:
A structured surface coating is electrochemically deposited on an electrically conductive surface of a component. The component to be coated forms the cathode in a galvanic bath. The process current is raised in discrete steps in a nucleation phase during which island formations are deposited on the surface, with brief pauses between each increase of between 0.1 and 30 sec. The process current is then maintained at a constant level, during which the islands grow. The process sequence may be repeated several times.
