Topic > The corrosion process

Corrosion is the result of electrochemical reactions between materials and substances in a certain environment (Capeman, 2018). Corrosion occurs through two processes, called oxidation and reduction. Oxidation is the transfer of electrons from one atom to another (Capeman, 2018). Reduction is a chemical reaction in which an atom gains an electron from the reaction. When oxidized atoms are on a surface, they begin to damage the surface of the metal as it becomes unstable due to the metal's reactions with the environment (Capeman, 2018). Within the two corrosion processes, there are two different types. Corrosion can occur in the entire general area of ​​the metal, known as generalized corrosion, or it can be highly concentrated in a local point, called localized corrosion (Frankel, 2008).

It leads to thinning of the metal and ultimately deterioration (Frankel, 2008). Localized corrosion is more harmful and harmful to the metal. In this process, rust attack occurs in a single area and creates a “cavity” within the metal (Frankel, 2008). Localized corrosion is difficult to prevent and slow down because corrosion detection occurs after the structure has been compromised and cracked. Of the two types of corrosion, generalized corrosion is less common than localized corrosion because it is unusual for an entire surface of a metal to be completely exposed and attacked by the specific acids causing the corrosion (Frankel, 2008). over time, a certain area or part is heavily weighted and affected by the acid which causes corrosion to occur more in that area. Some metals resist corrosion when the process collides with oxygen. The metal creates a thin oxide film that prevents corrosion from continuing (Corrosion Prevention, n.d.). The oxide surrounds the metal and creates a barrier, hindering any further reaction with oxygen. If the oxide film is damaged due to stress, the metal will corrode strongly concentrating in that specific vulnerable area (Corrosion Prevention, n.d.). Please note: this is just a sample.

Sometimes, because the reaction is so slow, corrosion is not evident (Venkateswaran, 2014). For metals prone to rust and corrosion, non-metallic coatings such as paint and oil can help slow or prevent the process (Venkateswaran, 2014). However, most metals oxidize easily and are prone to corrosion because they tend to lose electrons to oxygen in air and water (Capeman, 2018). When these oxygen atoms gain electrons, or “reduce,” they begin to form an oxide with the metal's surface, which ultimately results in corrosion. Works Cited Capeman, J. (2018).
