A thick layer of polyaniline is evenly and efficiently deposited on the surface as well as the edges of an anode porous metal. A porous film-forming metal or porous valve metal is immersed in an anilinum protonic salt solution of a high temperature and a high concentration, thereafter, anilinum protonic salt crystals are deposited on the surface of the porous metal by cooling the porous metal to or below the dissolution temperature of the solution, and the porous metal is immersed in an oxidant solution.

A corrosion inhibiting composition is provided which comprises a salt of a fatty acid-amine condensate and an aromatic solvent. The composition can be used in reducing, inhibiting or preventing corrosion of a metal surface used in recovery, transportation, refining or storage of a hydrocarbon fluid containing elemental sulfur or polysulfide.
