Adhesion Imrovement with Plasma Activation Between Aluminum Alloys

Abstract

Aluminum alloys are advantageous light metals in many respects. In the use of these alloys in the ship, aviation and automotive industries, bonding applications rather than welded joints or mechanical connections are preferred. Improving adhesion properties with various surface treatments applied to aluminum alloys is an important issue. Adhesive type, front surface treatments and surface activation techniques control adhesion strength. In this study, the effect of plasma surface treatment technology on adhesion strength was examined in detail. The water drop wetting ability of the alloys were examined, and then adhesion properties were compared with adhesion tests. It has been determined that plasma technology significantly increases the adhesion strength.
