← ScienceWhich outcome accelerates corrosion in marine steel pilings?
A)Formation of galvanic microcells on surface✓
B)Passivation layer of chromium oxides forms
C)Cathodic protection prevents active oxidation
D)Deposition of a uniform zinc coating
💡 Explanation
Galvanic corrosion accelerates because **electrochemical potential differences** establish ionic electrical circuits, therefore localized oxidation increases near cathodes rather than uniform breakdown because passivation or cathodic protection would prevent this process.
