Beschreibung
Zusammenfassung:	The present invention relates to: a rust-proofing treatment method comprising the step of treating an object that comprises a metal or an alloy and is heated to a temperature higher than 180°C or an object that has, formed on the surface thereof, a film or layer comprising a metal or an alloy and is heated to a temperature higher than 180°C with an aqueous solution containing an inorganic acid or an inorganic salt, or comprising the step of treating an object comprising a metal or an alloy or an object having, formed on the surface thereof, a film or layer comprising a metal or an alloy with an aqueous solution containing at least one component selected from silicic acid, a silicic acid salt, phosphoric acid, a phosphoric acid salt, a monohydrogen phosphate salt, a dihydrogen phosphate salt and a zirconium salt; and an article characterized by being rust-proofing-treated by the rust-proofing treatment method.
