| titleOfInvention | An aqueous acidic composition for forming a chemical conversion film containing chromium on an iron-based member, and an iron-based member having a chemical conversion film formed by the composition |
| abstract | An aqueous acidic composition for forming a chemical conversion film containing trivalent chromium on a member having an iron-based metal surface is provided. The composition contains a water-soluble trivalent chromium-containing substance, a water-soluble zinc-containing substance, and a water-soluble polyvalent carboxylic acid compound. Based on the total composition, the content of the water-soluble trivalent chromium-containing substance is It is 60 mmol / L or more in terms of chromium, and the zinc-equivalent molar content of the water-soluble zinc-containing substance is such that the ratio of the content to the chromium-equivalent molar content of the water-soluble trivalent chromium-containing substance is 0.6 or more. Yes, the content of the water-soluble polycarboxylic acid compound is 55 mmol / L or more in terms of polyvalent carboxylic acid, and is allylamine, polyallylamine, aromatic sulfonic acid, aromatic sulfonic acid-formaldehyde condensate and derivatives thereof, In addition, a water-based acidic composition is characterized in that a fluorine-based material, a hexavalent chromium-containing material, and a film-forming organic component are not added.
