Abstract (en)
A zinc-containing metal-plated composite steel article having an enhanced paint-coating property has 0.3 to 3.0 g/m<2> of a zinc phosphate composite coating layer formed on a zinc-containing metal-plated steel substrate by a cathodic electrolysis treatment or a first chemical conversion treatment and including zinc and phosphorus in a weight ratio Zn/P of 2.504:1 to 3.166:1 and 0.06 to 9.0% by weight of Fe, Co, Ni, Ca, Mg and/or Mn, and a phosphate chemical conversion layer formed on the composite coating layer by a second chemical conversion treatment and including fine phosphate crystals.
