Abstract
The present invention describes an innovative means of inhibiting corrosion of metals which experience active-passive transition in contact with an electrolyte. This invention incorporates hydrogen peroxide and/or peroxycarboxylic acids or their constituents to inhibit corrosion by inducing passivation of the metal. Application of this technology reduces the potential for fouling, scaling and deposition as well as outperforming existing methods of corrosion control in these applications.
Claims7
A method of inhibition of corrosion of a metal which experiences active-passive transition while in contact wit an electrolyte comprising:
- incorporating one or more peroxycarboxylic acids or their constituents with said electrolyte at a concentration effective to passivate the surface of the metal;
- and
- determining an activity factor of the metal.
