Patent ID: 8277870

Claim:
A method of controlling corrosion at an interface formed between at least two metal components, the method comprising: applying a blend of magnesium particles and one of an adhesive or a sealant to the interface, each of the magnesium particles having a diameter sufficient to span a distance extending from one of the at least two components at the interface to an other of the at least two components at the interface; and exposing the at least two components to a substantially corrosive environment, the substantially corrosive environment including a corrosive species that at least partially dissolves the magnesium particles at the interface to: i) cathodically protect the at least two components at the interface; ii) alkalize the corrosive species at the interface, the alkalizing including: hydrolyzing magnesium ions produced from the at least partial dissolution of the magnesium particles; and generating hydroxyl ions from the hydrolyzing, the hydroxyl ions to react with and alkalize the corrosive species; and iii) generate hydrogen bubbles that substantially block a crevice formed at the interface.
