Question

1)What is galvanisation? 2) What is anodisiong?

Answer 1

1.glavanisation
glavanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
2.anodisiong
Anodizingis an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.The process is called anodizing because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.

Answer 2

Answer:

Galvanisation:

• Galvanisation means applying a coating of zinc on steel or iron to protect it from rusting.

Anodising:

• Anodising is a process used to increase the thickness of the natural oxide layer on the surface of metal parts. .
