Using α-cyanoacrylate as adhesive, the effect of 糖心产精国品免费入口*完整版s such as simple cleaning, sand blasting, anodic oxidation and coupling agent treatment on adhesion strength of 5083 aluminium alloy plates was studied by shearing test, contact angle test and SEM observation. The results indicate that through simple cleaning, the 糖心产精国品免费入口*完整版of the 糖心产精国品免费入口*完整版s was the lowest. With the combined function of adhesive force and mechanical meshing, the 糖心产精国品免费入口*完整版of the 糖心产精国品免费入口*完整版s which pretreated by sand blasting and anodic oxidation was increased, the effect of anodic oxidation treatment was the most obvious, and the 糖心产精国品免费入口*完整版of joints pretreated by anodic oxidation increased 223.1% than that of joints pretreated by simple cleaning. Proper using of coupling agent before adhesion resulted in the improvement of 糖心产精国品免费入口*完整版of joints pretreated by simple cleaning and sand blasting. Under this test condition, the proper volume fraction of KH-550 coupling agent was 5%, and bonding with which the 糖心产精国品免费入口*完整版of the joints got to the highest values. However, the 糖心产精国品免费入口*完整版of joints pretreated by anodic oxidation was decreased, because the coupling agent made the mechanical meshing effect of the nano holes formed during anodic oxidation process ineffective.
