Question

which process is done to prevent corrosion of iron object​

Answer 1

Answer:

One way to prevent, or slow, corrosion is by coating the metal. Coating prevents water and oxygen from contacting the metal. Paint or other coatings will slow corrosion, but they are not effective once scratched. Zinc-plated or galvanized iron exploits the fact that zinc is more likely to oxidize than iron.

Answer 2

Answer:

There are many process which are done to prevent rusting of Iron , they includes :-

✳Painting ✳

Painting can check rusting as paint will slow down rusting by preventing moisture from reaching the metal.

✳Alloying ✳

Use of steel an alloy whose main constituent is steel can be used to prevent rusting because steel is a rust resistant material.

✳Galvanization✳

Galvanization is the process of coating zinc a rust resistant metal over iron objects to prevent those objects from rust.

✳Greasing and Oiling✳

Applying grease and over iron object will prevent attack of rust on objects as it blocks moisture.

✩RUSTING OF IRON✩

Rusting of iron is the chemical process by Iron forms Iron oxide when it comes in contact with air and moisture.
