Corrosion is the reaction to electrochemical reactions between elements and chemicals in a selected environment (Capeman, 2018). Corrosion happens through two procedures, called oxidation process and lowering. Oxidation may be the transferring of electrons from one atom to the other (Capeman, 2018). Lowering is a chemical reaction in which a great atom benefits an electron from the reaction. When oxidized atoms are on a surface, they begin to damage the top of metal since it becomes unpredictable because of the material experiencing reactions with the environment (Capeman, 2018). Within the two processes of corrosion, there are two different kinds. Corrosion can occur in the overall general area of the metal, called generalized corrosion, or it is usually heavily focused in one community spot, which is called localized corrosion (Frankel, 2008).

The generalized corrosion is rare because the rusting and corroding of the entire surface of one metal is definitely unlikely. This leads to the thinning with the metal and the end, degeneration (Frankel, 2008). Localized corrosion is more damaging and destroying to the metallic. In this method, the attack of corroding happens in one single region and makes a ‘cavity’ inside the metal (Frankel, 2008). Localized corrosion is difficult to prevent and decelerate because the recognition of the corrosion happens after the structure continues to be compromised and cracked. From the two types of corrosion, general corrosion is much less common when compared to localized corrosion because it is unusual for a whole surface of the metal to be completely uncovered and attacked by the specific acids that cause corrosion (Frankel, 2008).

Most of the time, a certain place or portion is greatly weighted and affected by the amount of acid which causes the corrosion to happen more because area. A few metals withstand corrosion if the process collides with fresh air. The metal creates a slim oxide film which prevents the corrosion to move forward (Corrosion Prevention, n. m. ). The oxide wraps around the metallic and provides an impressive barrier, obstructing any other reaction with fresh air. If the o2 film turns into damaged as a result of stress, the metal will corrode seriously concentrated because specific, weak area (Corrosion Prevention, in. d. ).

Most metals react to corrosion with oxygen, however, not all. Occasionally, because the reaction is so slower, the corrosion isn’t noticeable (Venkateswaran, 2014). For this kind of metals that are prone to rust and corrosion, nonmetallic films such as paint and essential oil can assist in slowing down or perhaps preventing the procedure (Venkateswaran, 2014). However , many metals can be oxidized and are also subjects to corrosion because they tend to get rid of electrons to oxygen surrounding this time and drinking water (Capeman, 2018). As these o2 atoms gain electrons, or perhaps ‘reduce’, they start to form an oxide with the surface of the metal, which in turn ultimately brings about corrosion.
