Appl. No.:

09/977531

Assignee:

The United States of America as represented by the Administrator of the National Aeronautics Space Administration - Washington DC

International Classification:

C23F 1300

US Classification:

205734, 205740, 106640, 106772, 106775, 106801, 10628403, 1062843, 1062862, 1062866, 1062868

Abstract:

Coating compositions and methods of their use are described herein for the reduction of corrosion in imbedded metal structures. The coatings are applied as liquids to an external surface of a substrate in which the metal structures are imbedded. The coatings are subsequently allowed to dry. The liquid applied coatings provide galvanic protection to the imbedded metal structures. Continued protection can be maintained with periodic reapplication of the coating compositions, as necessary, to maintain electrical continuity. Because the coatings may be applied using methods similar to standard paints, and because the coatings are applied to external surfaces of the substrates in which the metal structures are imbedded, the corresponding corrosion protection may be easily maintained. The coating compositions are particularly useful in the protection of metal-reinforced concrete.
