Abstract
Official abstract text for this publication.
A metal component made of a base metal and a coating system thereon is characterized in that the coating system comprises a conductive layer on the base metal and a resin-based layer including conductive pigments on the conductive layer. The conductive pigments form electrically conductive 3D-networks in the resin, with the networks being randomly distributed in the resin. Further, a method for coating a metal component is disclosed, and may include depositing a conductive layer on a surface of the component, depositing a resin with electrically conductive pigments on the conductive layer and drying the resin. The coating system may be applied to metal components, including aerospace fasteners such as pins, bolts, collars, nuts and nut plates, and washers, as well as studs, latches, helicopter rotors, and landing gear structures.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The method according to claim 1 , wherein the conductive layer is a nickel flash deposited on the surface of the metal component. 3. The method according to claim 2 , wherein the nickel flash is electrodeposited on the surface of the metal component. 4. The method according to claim 1 , wherein the liquid mixture is deposited on the conductive layer by spraying. 5. The method according to claim 1 wherein the pigments are nickel fibers and a concentration of nickel fibers in the liquid mixture is within a range of about 5 wt % to less than 15 wt %.
