Rust is a term which is generally used for a chemical compound iron oxide (Fe2O3). It is formed when iron combines with oxygen or water. Rust poses a significant problem it has been with us since the very dawn of the Iron Age. It not only affects cars, metal furniture and other durable metal objects but also upsets many business setups. It is bad for the people who have shops in cellars. Cellars tend to dampen and the dampness leads to rust or mold. Rust decreases the life of an object and hence, it becomes importantly necessary to remove or prevent rust from occurring.
There are several measures available to control corrosion and prevent the formation of rust. This is called rust proofing. Cathode protection is one such method. It uses electro chemical techniques. Galvanizing is used most frequently these days. It consists of a metal, to be coated, with a thin layer of another metal, generally zinc. Zinc provides cathode protection to the underlying metal as it is more negative than iron. Another technique used to prevent rust is bluing. It provides resistance to rusting for small steel items, fire arms etc. In this the water displacing oil is rubbed onto the blued steel.
Rust decreases the life of any object. Thus, it is very important to take proactive prevention measures in order to inhibit the formation of rust on an object. There are various ways of accomplishing this. The commonest of them is to cover or paint the object with a material that prevents or does not support rust and acts as a rust remover. For an example, the objects are covered with craft and hobby enamels. It has a smooth and satin finish. The ingredients penetrate faster and last longer. It is usually used on wood, metal, wicker and crafts. It also has an excellent chip resistance and is durable. The antique copper and antique gold are also used to give a rich and beautiful look to the objects besides preventing corrosion.
