Answer:
Galvanization or galvanizing 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 the parts are submerged in a bath of molten zinc.
Anodising is an electrolytic process for producing thick oxide coatings, usually on aluminium and its alloys.
