Final answer:
To increase a surface's resistance to corrosion and improve paint bonding, it can be coated with a layer of a metal that is resistant to corrosion. For example, a tin can is made of iron coated with tin, which protects the iron from corrosion.
Step-by-step explanation:
One way to prevent corrosion is to protect the surface of metal. Covering the surface of a metal object with paint or oil will prevent corrosion by not allowing oxygen to contact it. Unfortunately, scratches in the paint or wearing off of the oil will allow the corrosion to begin. Corrosion-sensitive metals can also be coated with another metal that is resistant to corrosion. A "tin can" is actually made of iron coated with a thin layer of tin, which protects the iron.
