Hope it helps

Answer 2

The current prevention methods for corrosion are as follows :-

1. Using an inert/unreactive coating.
----------------------------------------------------------------
The most common method of protection simply painting the metal object. However, coatings such as concrete, plastic (PVC), fibreglass, rubber and bitumen can also be used. They all simply stop the oxygen and/or the water from coming into contact with
the metal.

2. Using a sacrificial (more reactive) metal.
---------------------------------------------------------------
Iron that is coated in zinc (i.e. galvanised iron) is also protected, even if the surface is scratched. This is because of the increased reactivity of zinc.

3. Using electricity.
----------------------------------------------------------------
Most motor vehicles and large sheet-metal objects get coated in surface rust during manufacture. It is removed by a quick dip in a tank of sulfuric acid.
