采用化学浸镀锌法，在铝合金表面去除氧化膜的同时覆盖锌膜，以此改变铝合金表面的氧化状态，为实现大气环境、无中间合金条件下超塑成形／扩散连接（ＳＰＦ／ＤＢ）试验提供可能．结果表明，采用一定的浸镀液及工艺可获得最佳的表面覆盖效果；覆盖于连接表面的锌膜，改善了铝合金表面的氧化状态，且锌元素参与了连接过程的金属间互扩散，实现了大气无保护气氛条件下的超塑成形／扩散连接．
The chemical immersion zinc method is used to cover the zinc film while removing the oxide film on the surface of the aluminum alloy so as to change the oxidation state of the aluminum alloy surface. In order to realize the atmospheric environment, the superplastic forming / diffusion bonding (SPF / DB Test provided possible. The results show that the optimum surface coverage can be obtained by using a certain amount of immersion solution and the process; the zinc film covering the connection surface improves the oxidation state of the aluminum alloy surface, and the zinc participates in interdiffusion of the metal during the connection process, A superplastic forming / diffusion bonding under atmospheric unprotected atmosphere was achieved.
