Abstract

TA1 P-Ti/AA6061 composite plate was produced by oxidizing the surface of the titanium plate and adopting a cold roll bonding process. The results revealed that the oxide film (Ti₆O) prepared on the surface of TA1 pure titanium was easy to crack during the cold roll bonding, thereby promoting the formation of an effective mechanical interlock at the interface, which can effectively reduce the minimum reduction rate of the composite plates produced by cold rolling of titanium and aluminium plates. Moreover, the composite plate subjected to oxidation treatment exhibited high shear strength, particularly at a 43% reduction rate, achieving a commendable value of 117 MPa. Based on oxidation treatment and different reduction rates, the annealed composite plates at temperatures of 400, 450, and 500 °C displayed favorable resistance to interface delamination, highlighting their remarkable strength−plasticity compatibility as evidenced by a maximum elongation of 31.845%.

通过表面氧化处理提高冷轧 TA1 P-Ti/AA6061 复合板材的粘接强度

TA1 P-Ti/AA6061 复合板是通过氧化钛板表面并采用冷轧粘合工艺制成的。结果表明，TA1 纯钛表面制备的氧化膜（Ti6O）在冷轧粘接过程中容易开裂，从而促进界面形成有效的机械互锁，可有效降低钛铝板冷轧复合板的最小减薄率。此外，经过氧化处理的复合板具有很高的剪切强度，尤其是在减薄率为 43% 的情况下，剪切强度达到了 117 兆帕。根据氧化处理和不同的还原率，在 400、450 和 500 °C 温度下退火的复合板显示出良好的抗界面分层能力，突出了其显著的强度-塑性兼容性，最大伸长率为 31.845%。
