JOINED STRUCTURE OF METALLIC MEMBER

摘要

PROBLEM TO BE SOLVED: To prevent damage of a joining structure of two metallic members resulting from galvanic corrosion by preventing generation of galvanic corrosion between a solder layer and the metallic members, in a joined structure where a first metallic member and a second metallic member are joined together at a mutual surface contact region via a solder layer. SOLUTION: Surface regions of both metallic members 11 and 12 except a joined region are coated with films 14a and 14b of a metal baser than the metal that forms the metallic members 11 and 12. The films 14a and 14b function as a consumable positive electrode for the solder layer 13 to prevent galvanic corrosion of the solder layer 13. COPYRIGHT: (C)2003,JPO
