▎ 摘　　要

NOVELTY - The method involves providing a substrate layer (102) and depositing a graphene layer (106) on the substrate layer. The boundary cappings are selectively deposited on defects (110) of the graphene layer to inhibit corrosion of the substrate layer at the defects. The boundary cappings are provided with boundary capping material with exposed portions. The boundary capping material is deposited directly on the substrate layer in the graphene layer. USE - Method for manufacturing electrical conductor. Can also be used as contact, terminal, pin, socket, eye-of-needle pin, micro-action pin, compliant pin, wire, cable braid, trace and pad used in electrical connector, cable and printed circuit board. ADVANTAGE - The corrosion resistance of the electrical conductor can be improved and manufacturing time of the electrical conductor can be shortened. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrical conductor. Electrical conductor (100) Substrate layer (102) Graphene layer (106) Defect (110) Top portion (116)
