The effect of trace metallic additives of Al-Fe-X on microstructure, glossiness and hardness of Zn electrodeposits was investigated by using sulfate bath. The preferred orientation of Zn deposits with Al-Fe additives was (10 l)(l:3,4,2), while that of Zn deposits with Al-Fe-X(Ni,Co) additives was either (002) or (002)＋(103)ㆍ(104) mixed orientation. The preferred orientation of Zn deposits with Al-Fe-Cr additives changed from (002)+(10 l) to (10 l) orientation with increasing amount of Al additive. The surface morphology of the Zn deposits was closely related to the preferred orientation of the deposits. The glossiness of Zn deposits with Al-Fe additives increased in comparison with that of pure Zn deposit. That of the Zn deposits with Al-Fe-X additives was related to the morphology of the deposits and changed according to type of additives. The hardness of Zn deposits with Al-Fe-X(Ni,Co,Cr) additives was noticeably higher than that of Zn deposits with Al-Fe additives.
