| Abstract |
The purpose of this study is to make clear the effects of Ni on the behavior of precipitate formation in Vi added galvanizing bath, which has various Ni contents from 0.03wt% to 0.5wt%. The morphology of the precipitate changed with Ni addition from a needle like rectangular ζ-phase to a globular polygonal Zn-Fe-Ni phase. Al addition in Ni containing Zn-bath resulted in forming the Al-Ni intermetallic compounds such as Al₃Ni₂ and Al₂Ni which consist most of top precipitates. In the range of higher content of 0.07wt% Vi in Zn-bath, Al-Ni intermetallic compound was formed sensitively with small amount of Al addition. |
