Abstract

Low melting metals are difficult to weld because it is vaporized. But epoxy resin make bonding possible using low melting material and dismissal materials. This study is to improve the bonding strength of epoxy and substrate by mechanical and electrochemical methods. In case of mechanical work, bonding strength is 17.6MPa and in case of pre-work, bonding strength is 15.3MPa. When anodizing and mechanical work is applied, bonding strength is 25.3Mpa is increased 165%. When anodizing is applied, bonding strength is 27.6Mpa.
