Abstract
A process for electrochemically depositing a structured surface layer on a component, such as a machine component, particularly a steel water cylinder of a printing press, is disclosed. The process comprises the steps of defining an electrical parameter, such as a potential and/or an electrical current, effecting an electro-chemical layer deposition; and depositing a surface layer on the component with a structured outer surface topography. The depositing step is performed by providing an initial pulse of the electrical parameter and forming a plurality of island formations of deposition material on a surface of the component to be electro-chemically coated, and subsequently providing a follow-up pulse of the electrical parameter and causing a growth of the deposition material on the plurality of islands for causing the structured outer surface topography.
