  • Methods for passivating a metal substrate and related coated metal substrates
    Patent number: 8262882
    Abstract: Disclosed are methods for passivating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods comprise the steps of autodepositing copper, silver, a IIIB metal and/or IVB metal onto at least a portion of the substrate, and simultaneously and/or immediately subsequently electrophoretically depositing on the substrate a curable, electrodepositable coating composition; wherein the copper, silver, IIB metal and/or IVB metal and the curable, electrodepositable coating composition are both contained within a single bath composition. The present invention also relates to coated substrates produced by the above methods.
