Zusammenfassung:A method for treating a substrate having an electrically conductive surface. The method includes: contacting at least a portion of the surface with a medium comprising at least one silicate and having a basic pH and wherein less than 5 wt% of chromates is present in the medium, introducing a current to said medium using a cathode and an anode wherein said surface is employed as the cathode under conditions and for a time sufficient to form a film comprising silica upon the surface; recovering a treated surface by removing said surface from the medium; and applying at least one coating which comprises latex, silanes, epoxies, silicone, amines, alkyds, urethanes or acrylics on the treated surface.
