摘　　要：利用高频超声波的软化效应焊接金属Ti上的碳纳米管,研究焊接时间对碳纳米管焊接效果的影响.结果表明,焊接时间太短,碳纳米管松散分布在Ti金属表面,不能与金属形成紧密接触;焊接时间过长,金属基体被破坏,同样达不到焊接要求.只有选择合适的焊接时间(0.1～10 s),才能使碳纳米管与Ti有效焊接,呈现较小的两端电阻.Ultrasonic softening effect was used to weld carbon nanotubes （CNTs） on Ti electrode, and the effects of welding time on CNT welding quality were studied. The results showed that CNTs loosely lay on the surface of the Ti substrate with a short welding time, and there was no intimate contact between CNTs and Ti ; while the welding time was too long, welding standard was not reached due to the destroyed electrodes. Only when proper welding time was chosen （0.1 - 10 s） , could effective welding with lower two-terminal resistance be realized.
