1. A method for coating a metal component comprising a base metal, the method comprising:
providing the metal component;
depositing a conductive layer on a surface of the metal component;
depositing a liquid mixture comprising electrically conductive pigments dispersed in a resin on the conductive layer, and
drying the liquid mixture to form a resin based-layer, such that the conductive pigments form electrically conductive 3D-networks in the resin based layer, such networks being randomly distributed in the resin based layer.
