... in Fig. 3 describes the thermodynamic stability of water and predicts what will occur on a metal surface in contact with water at the full range of potentials and pHs covered by the diagram. If a metal electrode is at a potential and pH below line (a), the water is in an unstable region, and with time...

Abstract Organic coatings (paints and plastic or rubber linings), metallic coatings, and nonmetallic inorganic coatings (conversion coatings, cements, ceramics, and glasses) are used in applications requiring corrosion protection. These coatings and linings may protect substrates by three basic...
