Pigments play an important role in controlling corrosion. Inhibitive pigments are extensively used since they protect the metal surface by modifying the environments. The protective effect of inhibiting pigments is mainly due to the formation of a passive oxide film and soluble inhibitive ions. The evaluations of the paints containing these inhibitive pigments such as chromates, phosphates, red lead and zinc dust by electrochemical, accelerated and field trials are described in this paper.
