Claim Text:
1. A method for producing a coated material having an oxidizable metal-containing coating, comprising the step of applying to a base material an oxidizable metal-containing coating fluid containing a particulate oxidizable metal, a carbon component, a thickener, and water using a coating apparatus comprising a preparation tank for preparing the coating fluid, a coating unit for applying the coating fluid to the base material, and transfer means connecting the preparation tank and the coating unit, the method further comprising a coating fluid preparation step in which a thickener solution prepared by dissolving the thickener in water, the particulate oxidizable metal, and the carbon component or an aqueous dispersion of the carbon component are put and mixed in the preparation tank to prepare the oxidizable metal-containing coating fluid, the particulate oxidizable metal being added to the thickener solution in the coating fluid preparation step, the coating apparatus further comprising, in its transfer means, a relay tank capable of temporarily storing the coating fluid to be fed from the preparation tank to the coating unit, so that the oxidizable metal-containing coating fluid in the preparation tank is fed to the coating unit through the relay tank.
