ABSTRACT:
This specification teaches a method of preparing an article which is electronically conductive and resistant to corrosive attack by molten polysulfide salts. The method is carried out by the following steps. A sheet of graphite foil is coated with an amorphous pyrolytic or glassy carbon to fill any openings in and/or through the graphite foil. A thin layer of aluminum metal is coated onto at least one side of the graphite foil. The aluminum metal coated side of the graphite foil is bonded to an aluminum surface of an electronically conductive material. In this manner, an electronically conductive article is formed which is resistant to corrosive attack by molten polysulfide salts.
