Question

what is corrsion and its prevention​

Answer 1

rusting of iron is called corrsion . corrsion occur due coming contact with air,and water.

prevention

prevention of any metal is applying paint on it .or applying zinc on it

Answer 2

Corrosion is a galvanic process that can be prevented using cathodic protection. The deterioration of metals through oxidation is a galvanic process called corrosion.

One simple way to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. Depending on the application, these metals can be used to reduce the need for additional corrosion protection.A more easily oxidized metal can be applied to a metal surface, thus providing cathodic protection of the surface.

Galvanising is a method of rust prevention. The iron or steel object is coated in a thin layer of zinc. This stops oxygen and water reaching the metal underneath - but the zinc also acts as a sacrificial metal . Zinc is more reactive than iron, so it oxidises in preference to the iron object.

Hope this helps you!!!
