The high purity zinc foil solder was used to weld ZK60 alloy in vacuum furnace brazing. DMI-5000 M metallographic scanning electron microscopy was used to investigate the effect of welding process parameters on the formaton of brazed seam. At the same time, Durascan-700 Automatic hardness tester was adopted to test the microhardness of the welded joint and XRD analyzer was used to analyze the microstructure ingredient. The results show that, after btrazing at445℃ for 45 s, the properties and microstructure ...
