In connection with corrosion of metals, passivation is the process that__________________?
Correct answer: C. Inhibits further deterioration
- A. Intensifies deterioration
- B. Changes the composition of the metal
- C. Inhibits further deterioration
- D. None of these
Explanation
Passivation forms a protective surface film, often an adherent oxide, that sharply reduces the rate of further corrosion. It therefore inhibits deterioration rather than intensifying it or necessarily changing the bulk metal composition.
