Biography
Hyacinth Vedage, Ph.D., is an analytical chemist whose research interests are in the electrochemistry area with special interests in inhibitor development and organic coatings to prevent corrosion. After graduating from Lehigh University she worked as a Research Scientist for ten years working on electrochemical methods to study failure mechanisms of metals due to corrosion and developing inorganic/organic coatings to reduce metal loss. Before joining the Cedar Crest faculty she taught as an adjunct professor at Lafayette College and Northampton Community College for several years. Presently she teaches the introductory chemistry course for nursing majors and Analytical Chemistry for chemistry majors.

Inorganic/organic inhibitor for corrosion of iron containing materials in sulfur environment
US 5279651 A
1994-01-18
An organic salt, 2,4 Diamino-6-mercapto pyrimidine sulfate, has been combined with oxysalts of group VB or IVB of the periodic table to provide inorganic/organic inhibitor formulations having excellent corrosion resistant characteristics.

The ability of a fluropolymer and an epoxy coating to protect steel against corrosion in 0.1 M H2SO4 at 60°C was evaluated by four techniques; (1) cathodic delamination, (2) tensile adhesion, (3) rate of blister formation, and (4) gas analysis of blisters...
Characterizing copper surfaces using a polysulfide reagent
Surface Technology
1984-01-01
Copper immersed in a 0.025 M Na2S4 solution at pH 11 turns black at a characteristic time that is controlled by the presence of films or contaminants on the copper surface. The color change occurs coincident with an abrupt change in the corrosion potential. It is hypothesized that the rate-controlling step is the conversion of elemental copper and/or copper (I) to the copper(II) valence state...
