Mechanism Study of Clad-Welding and Drawing Method for Copper Clad Aluminum Wire Metallurgical Bonding
Pages: 1-6
Year: Issue:  6
Journal: Electric Wire & Cable

Keyword:  铜包铝线冶金结合金属键合扩散结合拉拔临界减面率;
Abstract: 探讨了包覆焊接-拉拔法铜包铝线在拉拔工序中实现“金属键合”和退火加热工序中实现“扩散结合”的机理.研究了界面上脆性氧化膜对金属键合的影响以及脆性化合物中间相对扩散结合的影响.提出了减少金属键合的临界减面率和提高扩散结合强度和力学性能的工艺方法.
