Passivating alloys are_______________?
Correct answer: A. Cr, Al, Ti
- A. Cr, Al, Ti
- B. Cr, Mo, Ti
- C. Cr, Gold, Ti
- D. Cr, Fe, Ti
Explanation
Chromium, aluminium, and titanium readily form thin, adherent oxide films that protect the underlying alloy from further corrosion, producing passivation. Gold does not passivate in this way, and iron alone is not the defining element in this group.
