ABSTRACT:
This invention is directed to a coating method. In the preferred practice of this invention, the method includes the steps of selecting a ferrous substrate, such as steel sheet preferably containing a first coating having certain corrosion resistant and adhesion-promoting characteristics, applying thereto an outer coating of an organic resin containing a particulate metal selected from the group consisting of Al, Ni, Cr, Fe, Mn, Cu, Mo, Co, Ag, Au and alloys thereof, where the particle size of said metal or alloy is prefereably no more than about 10 microns, and applying thereover a cathodic electrophoretic coating at voltages of at least 300 V. The product of such method is corrosion resistant, free of craters or pores, and is readily welable prior to the application of said cathodic electrophoretic coating.
