Abstract
An electroless or electrolytic process for treating metallic surfaces is disclosed. The disclosed process exposes the metallic surface to a first medium comprising at least one silicate, and then to a second medium comprising colloidal silica (additional processing steps can be employed before, between and after exposure to the first and second mediums). The first and second mediums can be electrolytic or electroless.
