process for the production of zinc - nickel alloy coated sheet with excellent pressverformeigenschaften

摘要

A Zn-Ni alloy-plated steel sheet having stable moldability is produced by subjecting the plated surface of a Zn-Ni alloy (Ni content: 10 to 17 wt.%)-plated steel sheet to dipping, spraying or anodizing using a solution containing one or both of H2PO4- and HPO42-.
