Homework Answers
The reduction potential of the given metals are
Fe = -0.44 V
Au = +1.50 V
Cr = -0.74 V
Ba = -2.90 V
Pb = -0.13 V
Thus Ba and Cr has a lower reduction potential than Fe and can protect the Fe from galvanic corrosion. Pb cannot be used to protect Fe from corrosion because of the higher reduction potential than Fe. Au cannot offer galvanic protection to Fe. However, if completely covered over the Fe surface by plating, Au can protect Fe from corrosion, because it is less reactive than iron, and forms a barrier. The Au layer will act like a paint film and protect the iron from corroding even though it does reduce iron's propensity to be corroded
