Laser Micro-brazing of Stainless-Steel Wire and Pt Band with a Cu Interlayer

With rapid development of biomedical engineering, the fabrication of multifunctional biomedical device with the joining of dissimilar materials is drawing researchers’ interest [1]. Stainless steel (SS) and Pt are both widely used materials in micro-scale biomedical device due to their good mechanical properties and biocompatibility [2, 3]. The micro-joining between SS and Pt to combine their advantages is in high demand; however, few efforts have been made on this topic.
