Abstract: This invention provides a phosphating process that can form a film suitable for a cold forging foundation within 60 seconds and preferably 30 seconds or less. The process uses a treatment bath that is formed of a phosphate ion solution (H2PO4−+Zn2+), made by dissolving zinc in phosphoric acid, contains phosphoric acid (H3PO4), phosphate ions, zinc ions and nitrate ions, may contain at least one kind of metal ion selected from the group consisting of nickel ions, cobalt ions, copper ions, manganese ions and iron ions, and further contains 0.5 g/l or below of metal ions other than the film forming components. The process involves electrolytic treatment by applying a voltage between a metal as a positive electrode and a treated article as a negative electrode and forms a phosphate film on the surface of the treated article. The phosphate ion solution prepared by dissolving zinc in phosphoric acid (H2PO4−+Zn2+) is a solution obtained by dissolving 8 parts by mass to a maximum dissolution concentration of zinc in 100 parts by mass of phosphoric acid.

Abstract: A conventional zinc phosphate chemical conversion film formed on an iron article comprises zinc phosphate hydrates, i.e., Zn.sub.3 (PO.sub.4).sub.2.4H.sub.2 O and Zn.sub.2 Fe(PO.sub.4).sub.2.4H.sub.2 O. A novel chemical conversion film is mainly composed of Zn.sub.3 (PO.sub.4).sub.2.2H.sub.2.4H.sub.2 O. The ratio of ##EQU1## is from 0.3 to less than 1. The problems of conventional chemical conversion film arise due to 4 moles of water of crystallization of the zinc phosphates which desiccates at a baking temperature of the paint. The small amount of water of crystallization of Zn.sub.3 (PO.sub.4).sub.2.2H.sub.2 O provides an improved chemical conversion film with respect to the corrosion resistance and the like.
