Which metal is protected from corrosion by a process called anodizing, which forms a thick oxide layer on its surface?

💡 Solution & Explanation

Anodizing is an electrolytic passivation process that thickens the natural oxide layer on the surface of aluminum components, thereby significantly enhancing corrosion and wear resistance. Metals like iron corrode to form flaky rust rather than a protective barrier through this specific process. Metallurgy and corrosion prevention methods are standard topics in chemistry questions.
