Question

What is corrosion explain its advantages and disadvantages?

Answer 1

Answer:

Explanation:

Corrosion means degradation of material due to its reaction with its environment. Corrosion deteriorates physical properties of the metal

DISADVANTAGES OF CORROSION —

1. Weakens material due to prolonged corrosive action.

2. loss, contamination, and deterioration of the appearance of a material.

3. safety, health and environmental risks due to corrosion, especially in manufacturing plants.

4. Corrosion tends to vent in technical malfunctions in machines.

ADVANTAGES OF CORROSION —

1. Corrosion of a material has to be renewed, thus giving scope of continuous demand for materials.

2. Corrosion becomes advantageous when a surface produces an oxide film that will keep corrosion from proceeding further; which happens to aluminum metal.

Answer 2

Answer:

Corrosion refers to the degradation of a metal. It is a chemical reaction in which the metal reacts with atmospheric moisture and oxygen gas to form metallic oxides.

Some advantages of corrosion:

1. Surface corrosion forms an oxide layer. 2. It acts as a barrier for air and moisture and thereby preventing the inner metal from corrosion.

3. Some metals like zinc act as sacrificial anodes to prevent corrosion to other metals.

Disadvantages:

1. It reduces the purity of the metal a lot early.

2. It weakens the bond of the substances and causes them to break.
