Question

In which of the following cases, we observe the galvanic effect?

(a) Bolts and Nuts metal joining’s

(b) Piping arrangements

(c) Machinery of a different metal combination

(d) Bolts and nuts metal joining’s, piping arrangements and machinery of a different metal combinations

This question was addressed to me by my college professor while I was bunking the class.

This intriguing question comes from Principles topic in portion Corrosion Principles of Corrosion Engineering

Answer 1

Correct answer is (d) Bolts and nuts metal joining’s, piping arrangements and machinery of a different metal combinations

The explanation is: The galvanic effect is due to the contact of two dissimilar metals in a conductive solution. The corrosion caused due to galvanic effect is known as galvanic corrosion. It can be usually observed at bolts and nuts metal joining’s, piping arrangements and machinery of different metal combinations.
