A Correct answer
Explanation

This is True. Anodizing is indeed an electrolytic passivation process that increases the thickness of the natural oxide layer on metal parts, primarily aluminum. The process enhances corrosion resistance, surface hardness, and allows for dyeing. The anodized layer becomes integral to the metal substrate, not just a coating.
