Question

defective coating of zinc over mild steel leads to

Answer 1

Using a coat of zinc over metals like steel is known as galvanization. this reduces the premature rusting and corrosion of metals. As zinc corrodes very slowly, it protects the metal that it coats. Also, as zinc forms bonds with the metal, it makes the object stronger and lesser prone to mechanical damage. In case there is a defective coating, these are some of the possible outcomes:

- Early rusting
- Breakage
- More maintenance
- Short life expectancy

Hope it helps :)

Answer 2

Answer:

Defective coating of zinc over mild steel leads to rusting.

Explanation:

• During the Galvanization process, zinc layer is coated on the surface of the metal to prevent the rusting.
• This decreases metal corrosion and premature rusting. It is protecting the metal which it coats as “zinc corrodes very slowly”.
• It also makes the metal will be stronger and less susceptible to mechanical harm as zinc forms bonds with the metal.  

• Hence, Defective coating of zinc over mild steel leads to rusting.
