Flux-free laser beam brazing by local deoxidation (A06)

该子项目的目的是将XHV-适当气氛下的无焊剂钎焊工艺转移和适应于铝-铜混合接头，从而加深对该工艺的理解。该工艺的鉴定基于对接头机械和电气性能的研究。除了对表面润湿性的调查外，还将调查导致增加对基材的热输入的影响。其他要研究的影响因素是焊锡丝上存在的氧化层和脱氧过程中引入的表面结构。

The aim of this subproject is to transfer and adapt the flux-free brazing processes under XHV-adequate atmosphere to the mixed aluminum-copper joint, and thus to deepen the understanding of the process. The qualification of the process is based on investigations of the mechanical and electrical properties of the joint. In addition to investigations on the wettability of the surfaces, effects leading to increased heat input into the base material will also be investigated. Other influencing factors to be investigated are the oxide layer present on the solder wire and the surface structure introduced in the deoxidation process.
