摘要：
Improved Zn-Ni-alloy-electroplated steel sheet can be prepared by electroplating steel sheet with an acid electroplating bath containing Zn ions, Ni ions and a small amount of titanium ions, preferably after pre-electroplating with an electroplating bath containing Zn ions and a larger amount of Ni ions and heating the plating sheet in the presence of water.
