What is corrosion and how can it be controlled ?Most of the metals are present in nature as combined state such as oxides, sulphate, sulphide, carbonate, halide, etc. These are minerals. The minerals from which metals are extracted profitably are called ore. Metals are extracted from their ore by a number of metallurgical operations which require energy. Therefore the extracted metals have a natural tenancy to go back to the combined state.
Corrosion is the destruction or decay of metals or any change in their property by the chemical or electro-chemical reaction with the environment. Environment may include soil, water, gases, acids, etc.
Corrosion is a major issue and there are many different methods to reduce it like: alloying, painting and many more. Do respond on how we can control this corrosion.
