METHOD FOR MANUFACTURING STRUCTURED CHROMIUM LAYERS

摘要

The invention relates to a method for producing structured chromium layers, in particular for media contact surfaces, wherein the structural chromium layer is produced by electrodepositing chromium from an electrolyte onto a substrate. The invention is based on the aim of creating a method for producing structured chromium layers for contact surfaces having improved characteristics compared to the known chromium coatings. Said aim is achieved in that the structural chromium layer is formed at constant current densities and in a temperature range that depends on the current density and in that the structure formation is initiated by at least one temperature change.
