摘 要:采用室温轧制复合法实验研究了锌/铝轧制复合时变形率和剥离强度的关系,通过界面电镜观测, 探讨了锌/铝轧制的复合机理,同时提出了锌/铝复合板的热处理应选择低温、短时退火制度,以200℃,20 min为宜 。
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.
