How We Can Prevent Rusting in Everyday Life

Have you ever noticed iron objects like gates, tools, or bicycles turning reddish-brown over time? This change is called rusting, and it slowly damages the metal if not prevented. Rusting is not just about appearance; it weakens iron and makes it less useful. That is why understanding its effects and how to prevent it is important.

This article provides insight into how rust forms on iron or around us and the different methods used to prevent it.

Effects of Rusting

Rusting changes the appearance of the iron articles. Due to rusting, they look reddish brown coloured and rough. Rust formed on the surface of a strong iron object falls off like a flaky powder, and then the iron below starts rusting. So, rusting is a slow and continuous process which eats up iron and makes it useless.

Prevention of rusting

Iron articles rust only if their surface comes in contact with moisture and air. So, rusting can be prevented when the surface of iron articles is coated or covered. Coating of the surface will arrest the direct contact of iron with moisture and air. Hence, inhibit the reaction of iron with moisture and air.

Rusting of iron can be prevented by the following methods:

Painting and greasing: It is the process of coating the surface of iron with paint or grease so that it does not come in direct contact with moisture or oxygen. This prevents rusting. First, the iron articles should be cleaned and then painted with anti-rust paint, or a protective layer of grease has to be applied. Window grills, iron bridges, bodies of trucks, buses and cars are all painted to prevent them from rusting.

Galvanisation: The process of depositing a coating (or thin layer) of zinc metal on iron objects is known as galvanisation. Water supply pipes are galvanised with a protective layer of metals such as zinc or chromium to protect them from rusting.

Tinning: It is the process of coating an iron surface with tin to protect it from rusting.

Use of alloy: When two or more metals or a metal and a non-metal are liquefied and mixed homogenously, the process is called alloying. The alloys formed are more resistant to corrosion. The alloys of iron, such as stainless steel, are resistant to rusting.

Enamelling: Enamel is a mixture of iron or steel with silicates. Objects like iron pots, pans and cooking appliances are enamelled to prevent rusting.

Electroplating: It is the process in which metals like tin, nickel and chromium, which do not corrode, are electroplated on iron. Bathroom fittings and bicycle handles made of iron and steel are electroplated with chromium to protect them from rusting.
