Question 10 For the tin plated steel : Tin is more anodic than steel, and once the steel is exposed the tin corrodes Tin is more cathodic than steel and once the steel is exposed the steel will corrode There is a small cathode /large anode situation here meaning the steel will corrode quickly There is a small cathode /large anode situation here meaning the tin will corrode quickly
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.
