Abstract
The synergistic behaviour of molybdate and phosphate ions in mitigating the corrosion
of mild steel in simulated cooling water was evaluated performing potentiodynamic polarization
and impedance spectroscopy tests. Phosphate and molybdate showed a synergistic effect on
corrosion inhibition of steel in simulated cooling water. The observed reduction in anodic and
cathodic current densities could be the consequence of incorporation of both phosphate and
molybdate ions in forming a protective layer on the surface. The charge transfer resistance of the
protective layer formed on steel surface was much greater in presence of both ions in solution than
that when each inhibitor used alone.
