Abstract:Characteristic bonding of Al/Zn sheets by cold rolling was studied. With the given data and SEM photographs, the following conclusions were obtained: During the process of rolling, virgin aluminum extrudes through cracks, and bonds are formed with oxidized and contaminated surfaces of Zn; to obtain good bonding strength, heat treatment of Zn/Al clad materials should be at a low temperature for a short time, especially at 200℃for 20min.
Key words: clad rolling critical deformation bonding strength
