Abstract: A sealing interface configured to prevent galvanic corrosion of a container having parts made of dissimilar materials includes a first part, a second part, and a sealant. The first part has a first sealing surface and a first exterior surface substantially perpendicular to the first sealing surface. The second part has a second sealing surface and a second exterior surface substantially perpendicular to the second sealing surface. One of the parts includes an external sealing chamfer on the respective sealing surface extending to the respective exterior surface. The sealant at least fills a space formed between the external sealing chamfer and the sealing surface of the other of the parts when the parts are connected, forming a barrier between the parts such that the exterior surfaces of the parts are not in contact and are separated by the sealant. The exterior surfaces may be flush when the parts are connected.

Abstract: In an example of a method disclosed herein, a polycarbonate with a hydrophilic surface is formed. An ether substituted dichlorosilane, phosgene, and a Bisphenol reactant are polymerized to form a polycarbonate including a hydrolyzable silane in its backbone chain. The hydrolyzable silane includes an alkoxy group attached to a silicon atom. The alkoxy group on the hydrolyzable silane is converted to a more hydrophilic functional group to form the polycarbonate with the hydrophilic surface.

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.
