Abstract

The invention relates to a component made from a substrate with a coating, whereby that coating forms a surface of the component with reduced wettability. The invention further relates to production of said component. The coating which forms a surface with projections and recesses, brings about a reduction in wettability, in particular, by means of an effect based on the properties of lotus blossom. According to the invention, a metal with antimicrobial properties, in particular silver is provided under the coating, which is not fully covered, in other words, regions remain free of the coating in which the surface of the component is formed by the antimicrobial properties.
