Which of the following is not a method used to protect iron objects from corrosion? O Apply a protective coating of a metal that is more difficult to oxidize. O Apply a coating of a sacrificial metal on top of the iron surface. O Allow a thin coating of iron oxide to form as a protective layer. O Apply a coating of a nonconductive material to the surface of the metal.
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.
