Question

Which of the following best explains why anodization is a useful process in many industries? Anodization can improve the appearance of dull metals by adding layers of gold or silver to them. Anodization can create a thin film around metals, preventing rusting and other forms of corrosion. Anodization can split water molecules into a clean-burning and relatively inexpensive source of fuel. Anodization can refine impure copper to produce pure copper, a metal used in pipes, wires, and many other applications.

Answer 1

The correct answer is that anodization can produce a thin film around the metals, preventing rusting and other kinds of corrosion.  

Anodizing refers to an electrolytic passivation procedure used to enhance the thickness of the natural oxide layer on the metal parts surface. The procedure is known as anodizing as the section to be treated produces the anode electrode of an electrolyte cell. The process enhances resistance to corrosion and rusting.
