← TechnologyWhat type of corrosion occurs when chloride ions compromise the passivation layer on rebar?
A)Pitting corrosion propagates rapidly✓
B)Uniform corrosion is evenly distributed
C)Galvanic corrosion impairs metal junctions
D)Erosion corrosion induces component damage
💡 Explanation
Pitting corrosion occurs due to chloride intrusion, because the **depassivation** mechanism creates anodic and cathodic areas. These areas accelerate localized corrosion, therefore leading to quicker structural weakening of reinforced concrete, rather than uniformly distributed metal thinning.
