where \(I\) is the total current, \(i\) is the current density, and \(A\) is the surface area.

Using the cathodic protection equation:

t = 0.1 mm/year 10 mm ​ = 100 years A stainless steel tank is used to store a corrosive chemical, and pitting corrosion is observed. The pit depth is measured to be 5 mm, and the corrosion rate is estimated to be 0.5 mm/year. How long will it take for the pit to penetrate the tank wall? where \(I\) is the total current, \(i\) is

I = i × A

t = r d ​

t = r d ​
