Abstract:
A method of mitigating galvanic corrosion on a vehicle is provided for use of metals with carbon containing composites. An electrically conductive material comprising a plurality of electrically conductive metallic particles and a polymer is applied to a corrosion susceptible region of an assembly having a carbon-reinforced composite and a metal. The electrically conductive material has an electrical conductivity of greater than or equal to about 1×10−4 S/m and serves as a sacrificial anode to mitigate or prevent corrosion of the metal in the assembly. Also provided are assemblies for a vehicle having reduced galvanic corrosion that include a metal component in contact with a carbon-reinforced composite, which defines a corrosion susceptible region having an electrically conductive material disposed therein.
