Abstract
A method of detecting a cathodic corrosion site on a metallized substrate comprises depositing molecules of a pH sensitive fluorescent dye adjacent a metallic surface of the substrate, the metallic surface having a corrosion site thereon characterized by a reduction of the hydronium ion to hydrogen (2H.sup.+ +2e.sup.- .fwdarw.H.sub.2). An electrical bias is then applied across the metallic surface, and the fluorescent dye is exposed to ultraviolet (UV) radiation, whereby fluorescence is activated at the cathodic corrosion site.
