Abstract

The influence of surface activated bonding (SAB) on the adhesion strength between Aluminum metal foil and Al₂O₃ ceramic sheet is investigated. A series of Al/Al₂O₃ laminates were successfully prepared using SAB. After plasma pre-treatments with increasing power and higher vacuum, the surface roughness and contact angle of Al and Al₂O₃ are significantly decreased, resulting in a large contact area between Al and Al₂O₃. The adhesion strength between Al and Al₂O₃ after plasma pre-treatment is dependent on the bonding pressure during SAB. A higher adhesion strength may also be related to the enlarged contact area between the highly activated surfaces of Al and Al₂O₃. It was concluded that the conditions used during the plasma pre-treatment and the bonding pressure selected during SAB are important factors in determining the adhesion strength between Al and Al₂O₃.
