Summary: | A composition for selective anodization, comprising the substances amidosulphuric acid, magnesium sulphate and concentrated sulphuric acid as a base electrolyte and additionally sodium stannate and/or molybdenum oxide. A corresponding method of selectively anodizing a substrate or workpiece includes providing a substrate having a surface which is to be selectively coated, where the substrate is arranged in a tool and forms a coating cell, selectively bathing the surface with the composition for selective anodization, and applying an electric current between substrate (anode) and tool (cathode) for selective anodization of the surface. |
