Abstract (en)
The present invention relates to a cathodic electrodeposition medium for forming a deposit on the surface of a metallic or conductive surface. The medium comprises a combination of water, silica, at least one water soluble silicate, and at least one water soluble dopant wherein the medium has a basic pH. The resulting deposit imparts improved corrosion resistance to the underlying substrate. In the preferred embodiment, the medium comprises sodium silicate and has a pH of greater than approximately 10. <IMAGE>
