Abstract This invention relates to a treatment method for brass atmospheric corrosion-proof surface. It is characterized by that an object has a passivated substrate of passivation treatment and coating treatment is further applied to the substrate, an organic coating is sprayed on the object for 1-4 times, each spray is 24-48 min interval and is dried at room temp., then the spray-coated object is thermoinsulated in an over at 100-120 deg.C for 1-3h, and is cooled to room temp.. Its advantages are no pollution to environment, no harm to the health of operation personnel and the obtained ideal protective effect.
