(b) Figure 1 shows four metal plates placed in contact with one another in order. Two metal plates were made of Metal A, one was made of Metal B and one made of Metal C. If corrosion only occurred at the following (blue) shaded areas, predict what are metal plates 1, 2, 3 and 4 made of. Between Metal A, B and C, explain which is most anodic and which is most cathodic? Metal Metal Metal Metal Plate Plate Plate Plate 1 2 3 4 Figure 1
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
