摘要

本文采用搅拌摩擦点焊（FSSW）技术将 7075 Al 合金与聚酰亚胺（PI）板连接起来。研究了 FSSW 参数和激光纹理对 Al/PI 接头微观结构和拉伸剪切载荷的影响。最佳的 FSSW 参数为：转速 2400 r/min、切入深度 0.4 mm、停留时间 20 s、切入速度 10 mm/min。铝合金表面的激光纹理增加了接头的拉伸剪切载荷。横截面显示，铝合金和 PI 之间存在机械锁定。XPS 结果表明，激光纹理产生后，焊接界面没有形成化学键。Al 7075 和 PI 的连接机制主要是机械锁定。

Effects of the processing parameters and laser textures in friction stir spot welding of Al alloy and polyimide joints

In this paper, friction stir spot welding (FSSW) technology was introduced to join 7075 Al alloy to polyimide (PI) sheets. The effects of the FSSW parameters and laser textures on the microstructure and tensile shear load of the Al/PI joint were studied. The optimum FSSW parameters were the rotation speed of 2400 r/min, the plunge depth of 0.4 mm, the dwell time of 20 s, and the plunge speed of 10 mm/min. The tensile shear load of the joint increased owing to the laser textures in the Al alloy surface. Cross-sections showed that the mechanical locking was found between the Al alloy and PI. The XPS results revealed that no chemical bond were formed at the welding interface after laser textures. The joining mechanism of Al 7075 and PI was main the mechanical locking.

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
