Final answer:
Galvanization is the process of coating iron or steel with a layer of zinc on both sides to prevent rusting, with the zinc layer providing cathodic protection and inhibiting further corrosion. So, the best answer is b, Zinc coated on 2 sides
Step-by-step explanation:
The term galvanized typically refers to the process of coating iron or steel with a thin layer of zinc to prevent rusting. The correct answer to the question is B. Zinc coated on 2 sides.
This galvanization process involves the metal being dipped into molten zinc, creating a coating that covers all surfaces of the metal.
This zinc layer acts as anodic protection; it will corrode before the iron or steel does, offering cathodic protection which prevents the underlying metal from rusting.
Once exposed, the zinc layer develops a patina of zinc carbonate, which further inhibits corrosion of both the zinc and the underlying metal.
So, the best answer is b, Zinc coated on 2 sides
