Abstract
A permanently curved component consists of a coated substrate. The substrate is deformable, and the coating consists of multiple layers which are deposited one over another and each of which has layer elements lying adjacent to one another on a plane. The layer elements from adjacent layers are weakly connected together such that the layer elements can move relative to each other upon deforming the coated substrate. In order to produce such a component, the layer elements which lie one over another and which can consist of graphene are first deposited, and then the coated component is deformed such that a closed layer remains.

A permanently curved component comprising:
- a substrate (5) that is coated with a coating and is deformable;
- and
- the coating, wherein the coating comprises multiple layers (1, 2, 3, 4) which are deposited one over another, wherein each of the layers includes layer elements (11, 12, 13, 14) that lie adjacent to one another in a plane, wherein the layer elements (11, 12, 13, 14) from adjacent ones of the layers (1, 2, 3, 4) weakly connected together such that the layer elements (11, 12, 13, 14) from the adjacent layers are able to move relative to each other when the coated substrate (5) is deformed.
A method for producing deformed, coated components, the method comprising:
- depositing a coating on a substrate (5), wherein the coating comprises multiple layers (1, 2, 3, 4) which are arranged one over another and each has layer elements (11, 12, 13, 14) that lie adjacent to one another in a plane, and wherein the layer elements (11, 12, 13, 14) from adjacent ones of the layers (1, 2, 3, 4) are weakly connected together such that the layer elements (11, 12, 13, 14) from the adjacent layers are able to move relative to each other when the substrate (5) is deformed;
- and
- deforming the coated substrate (5) to produce a permanently deformed component.
A method for producing a coated component, the method comprising:
- depositing a coating on a deformable substrate (5), wherein the coating comprises multiple layers (1, 2, 3, 4) arranged one over another, each of the layers having multiple unconnected layer elements (11, 12, 13, 14) that lie adjacent to each other in a plane and have a two-dimensional character, and wherein the layer elements (11, 12, 13, 14) of adjacent ones of the layers are connected to each other via Van der Waals forces;
- and
- deforming the coated substrate (5) to produce a permanently deformed component, wherein a total number of the layers (1, 2, 3, 4) is selected such that after the deformation, during which the layer elements (11, 12, 13, 14) move relative to each other, no open areas of the substrate (5) are left, wherein deforming the coated substrate (5) comprises bending the coated substrate (5) with a bending radii between 0.1 mm and 5 mm.
