Abstract
Disclosed is a Zn-based composite-plated metallic material, comprising a plating layer on a metal substrate. The plating layer consists essentially of (1) Zn or as Zn alloy electroplated onto a metallic substrate and (2) the cathodic precipitation reaction product of aluminum, calcium, magnesium, strontium, titanium, zirconium, molybdenum, and/or tungsten. The latter metal constitutes 0.002 to 10% by weight of the plating layer. The cathodic precipitation-reaction product may be hydroxide, hydroxide hydrate or a phosphate.
