Question

Erosion corrosion results when the protective oxide films are damaged and the metal or alloy are attacked at a rapid rate.

(a) True

(b) False

I have been asked this question in exam.

My question is from Eight Forms in division Eight Forms of Corrosion of Corrosion Engineering

Answer 1

The correct choice is (a) True

For explanation I would say: As the relative movement of the corrosive solution and the surface of the metal increases the intensity of erosion-corrosion increases. At higher velocities, it results in the damage or worn out of oxide film and it attacks the metal rapidly.
