I- All anodic reactions on the metal surface being protected completely stop. Il- The direction of the current in the electrolyte is from the anode to the cathode. Ill- The current intensity passing through thecircuit depends on the potential difference between the anode and cathode andtheresistanceof the circuit. IV- The surface of the metal structure to be protected cathodically can be covered with a suitable material and the current requirement can be reduced. Which of the above / which are wrong?
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.
