Abstract
Abstract
Orthophosphoric acid solutions of sodium orthovanadate, sodium tungstate, and sodium molybdate are tested as potential corrosion inhibitors of the Al2Cu intermetallic phase. Corrosion inhibition is observed for 0.2 M solutions of Na3VO4 and Na2WO4 by increasing the pH to > 2. When the pH is < 2, the aforementioned salts increase the corrosion rate of the intermetallic phase. A 0.2 M solution of Na3VO4 causes the precipitation of vanadium phosphate on the surface of the Al2Cu phase at pH = 1.
