高濃度ジンケート浴におけるデンドライト抑制に及ぼすSnおよびInの影響

抄録

Zinc deposits obtained from the concentrated alkaline zincate bath always showed dendritic crystal. Whereas the bath added to Sn（IV）ion and/or In（III）ion inhibited dendritic crystal formation, the deposit obtained from the bath added to Sn（IV）ion showed block-like crystal formation. The deposit obtained from the bath containing In（III）ion showed a hexagonal, disc-shaped structure and steps on the edge of crystals, which led to the preferred orientation with the {10•2}, {10•3}, and {0•04} plane.
