| titleOfInvention | Composition for Chemical Conversion Treatment and Member Having a Chemical Conversion Film Formed by the Treatment |
| abstract | A chemical conversion treatment solution comprising, based on the total composition, 0.1 g/L to 3.0 g/L of an aqueous cobalt-containing substance in cobalt equivalent, 0.05 g/L to 3.0 g/L of a pyrogallol compound in pyrogallol equivalent, and at least 1.5 g/L of an aqueous trivalent chromium-containing substance in chromium equivalent, the composition being acidic and the ratio of the content of the pyrogallol compound in pyrogallol equivalent to the content of the aqueous cobalt-containing substance in cobalt equivalent being 0.015 to 10, wherein a chemical conversion film formed on the metallic surface of a member by contacting the metallic surface with the composition for chemical conversion treatment has a content of hexavalent chromium of 0.050 μg/cm 2 or less as measured by a method compliant with EN15205 after exposure to an environment having a temperature of 80° C. and a relative humidity of 100% for 72. hours. |
