METHOD FOR MANUFACTURING AN ALUMINUM-RESIN JOINED BODY AND ALUMINUM-RESIN JOINED BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an aluminum-resin joined body having an extremely high joining strength between an aluminum substrate and a resin member; and an aluminum-resin joined body.SOLUTION: In the provided method for manufacturing an aluminum-resin joined body, an etching gas including chlorine atom-containing gas molecules and water molecules is jetted, after having been mixed with a plasma jet, onto an aluminum substrate. A thermoplastic resin is induced to infiltrate multiple valley portions included among valley and peak portions of the aluminum substrate thus formed and then is solidified so as to obtain, by forming a fitting interface of the resin member, an aluminum-resin joined body in which the aluminum substrate and resin member are joined; an aluminum-resin joined body thus obtained is also provided.
