英文摘要	For friction stir spot welded (FSSW) magnesium-aluminium joints, the formation of Mg-Al intermetallics in the hook region and cracking at the interface damaged seriously the strength of Mg-Al joints, resulting in lower joint load of only 0.8 +/- 0.2kN. When adding the hot-dipped Zn coating on the Al substrate surface prior to FSSW, a brazed layer, composed of Mg-Zn and Al-Zn diffusion zones at the edge of the shoulder, and a transition layer, composed of MgZn2, Zn-rich zone and residual Zn in the hook region, were formed in the FSSW Mg-Al joint, eliminating the cracking and Mg-Al intermetallics in the FSSW joint without the Zn coating. The load of the joint with the Zn coating increased to 3.7 +/- 0.3kN.
