Question

Anodizing is done in case of:

Answer 1

1. The electrolytic process known as "anodizing," which is used to form thick oxide coatings on metals and alloys typically, is defined as one that uses an electrolyte.
2. A 5 to 30 μm thick oxide layer is created.
3. Improved corrosion and wear resistance on the surface is the result of this.
4. The treated metal is referred to as the anode in the electrolytic process and is submerged in a weak acidic solution.
5. Oxide layer formation results from the oxidation reaction occurring on the metal surface.
6. Aluminum is given a pre-treatment before the electrolytic procedure.
7. The benefits of the anodizing coating will be improved with the help of this pre-treatment. Polishing, machining, drilling, and welding are all part of the pre-treatment process.

Application of anodization

Below is an example of anodizing in use.

1. Anodizing gives the metal surface a protective covering.
2. Black films created by anodizing steel are utilized as decorative items.
3. Several color coatings are produced by anodizing zinc.
