A method for inhibiting corrosion, e.g., pitting corrosion, of alloys is provided. Particularly, the method comprises contacting at least a portion of a surface of the alloy with an aqueous solution comprising a salt of one or more rare earth elements selected from the group consisting of yttrium, gadolinium, cerium, europium, terbium, samarium, neodymium, praseodymium, lanthanum, holmium, ytterbium, dysprosium and erbium; and establishing a voltage differential between an anode comprising the alloy and a cathode in the solution at an effective level and for a sufficient period of time wherein a rare earth element oxide-containing coating is formed on the surface of the alloy to inhibit corrosion thereof. |
