| Summary: | Corrosion is the deterioration of a substance usually a metal or its properties because of a reaction with its environment (NACE, 1984). Corrosion is the unwanted or undesired loss of material due to a reaction of the material with its surrounding or environment. Corrosion also means the breaking down of essential properties in a material due to chemical reactions with its surroundings, which is in other word; corrosion means a loss of electrons of metals reacting with water and oxygen (Goel, 1986). Lost in production and material replacement due to corrosion mechanisms cost billions of dollars annually to industry. These economic losses can be divided into two groups which are called direct losses and indirect losses. The terms of direct losses means increasing of cost. The example of direct cost are costs of replacement of machinery and their component, costs of maintenance or servicing, costs of rebuilding or construction, costs for equipment capital, costs for environmental regulations, costs in chemical expenses and cost for safety considerations. While the term of indirect losses means a decreasing of revenue. Example of indirect losses is costs due to shut down, cost of lost production, costs due to loss of efficiency and costs resulting from catastrophes. |
