    摘要： The present invention is directed to a method for coating a substrate comprising: (a) applying a caustic cleaner onto at least a portion of the substrate; (b) rinsing at least a portion of the substrate that was subjected to step (a) with water; (c) applying an acid cleaner onto at least a portion of the caustically cleaned substrate; (d) rinsing at least a portion of the substrate that was subjected to step (c) with water; and (e) applying a conversion coating comprising zirconium onto at least a portion of the acid cleaned substrate; and wherein at least one of the materials used in steps (c) and (e) is substantially chrome free. The present invention is also directed to a substrate, such as an aluminum substrate, that has been coated using the aforementioned method.

    摘要： 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.
