Abstract
A metallic cast component includes at least one microstructured functional element on a predefined surface area of the component with a relief-shaped structure sized in a micrometer range in at least one spatial direction for realizing a particular function. The functional element has at least one characteristic dimension of a length of less than 100 μm.

A metallic cast component, comprising at least one microstructured functional element on a predefined surface area of the component with a relief-shaped structure sized in a micrometer range in at least one spatial direction for realizing a particular function, said functional element having at least one characteristic dimension of a length of less than 100 μm.
A component with at least one microstructured functional element, said component being produced by an investment casting method comprising the steps of:
- producing a microstructure at a predefined area on a cavity-confronting surface of a molding tool;
- introducing a substantially liquid metallic material in the cavity of the molding tool;
- and
- molding a component in the cavity of the molding tool, thereby reproducing on an outside surface of the component a positive of the microstructure to form a microstructured functional element so as to provide the component at a defined area with a relief-shaped structure sized in a micrometer range in at least one spatial direction for realizing a particular function,
- wherein the functional element has at least one characteristic dimension, with the characteristic dimension being a length of less than 100 μm.
