Abstract
The present invention is directed to a substrate with a coating of titanium suboxide thereon. The coating protects the substrate from corrosion. Typically, the substrate is a current collector for a lead acid battery. The present invention is also directed to a process for forming the coating of titanium suboxide coating on the substrate. A colloidal dispersion of titanium suboxide particles in water is formed. The pH of the colloidal dispersion is brought within the range of 3 or less. The substrate to be coated is then placed in the colloidal dispersion. A positive electrode is also placed in the colloidal dispersion. An electric field is then introduced into the colloidal dispersion to effect electrophoretic deposition of the titanium suboxide on the substrate.
