A copper sheet with a total surface area of 8200 cm? is exposed to an aerated corrosive environment. A total of 6 rivets made of iron were inserted in the copper sheet, each rivet has a diameter of 20 mm. The corrosion rate of the uncoupled iron is 0.2 mm/y. a) What form of corrosion would you expect? b) Calculate the corrosion rate of the coupled iron rivets in mm/y. Has this value of corrosion rate been expected? Justify your answer
