✦ Synopsis

The diffusion bonding of Mg and Al alloys with different interlayer compositions was investigated, where the interlayer was prepared through hot dipping technique in pure Zn, Zn-8Al and Zn-5Al baths, respectively. By means of microstructure characterization and strength measurement, it is found that the interlayer obtained in Zn-5Al bath led to the formation of interface microstructure composed of mini Al-rich particles dispersed in MgZn 2 phase, this kind of phases constituent decreases the risk of embrittlement of entire diffusion bonding joint and benefits its mechanical performance greatly.
