What is corrosion?
The Corrosion is an electrochemical process which causes the deterioration and degradation of various materials due to chemical reactions with their environment.
It is often associated with oxidation, although corrosion can occur without the presence of oxygen. This phenomenon can affect metals, alloys, ceramics, plastics and other materials used in numerous industries and applications.
During the corrosion process , materials can experience changes in their structure and physical properties, resulting in loss of strength, integrity and functionality.
The Corrosion can manifest itself in different ways , including surface deterioration, pitting, thickness loss and crack formation.
The The presence of water and oxygen is one of the main causes of corrosion . In the presence of moisture, metallic materials can form oxides, hydroxides or other corrosive products. These products can accelerate the corrosive process, especially in aggressive environments such as coastal or industrial areas.
Why corrosion occurs
The Corrosion arises due to a combination of chemical, electrochemical and environmental factors that interact with the exposed materials. Next, we will explore some of the main reasons why corrosion occurs:
- Electrochemical reactions : Corrosion is an electrochemical process in which oxidation and reduction reactions occur on the surface of the material. These reactions generate electrical currents that can accelerate the deterioration of the material. Metals, in particular, are susceptible to corrosion due to their ability to lose electrons and form positive ions in aqueous solutions.
- Presence of corrosive agents : Exposure to corrosive substances, such as acids, bases, salts, gases and aggressive chemicals, can accelerate the corrosive process. These agents can facilitate the electrochemical reaction and corrode the material more quickly and severely.
- Humidity : The presence of water is essential for corrosion to occur, as it acts as a conductive medium for electrochemical reactions. Humidity provides the ions necessary for oxidation and reduction reactions to occur, leading to material deterioration.
- Oxygen : Oxygen in the air is another critical factor in corrosion, as it promotes the oxidation of metals. The presence of oxygen facilitates the formation of oxides on the surface of the material, which weakens its structure and contributes to the corrosive process.
- Temperature variations : Temperature changes can influence the rate and intensity of corrosion. For example, the cycle of thermal expansion and contraction can generate stresses in the material, which weakens its resistance and encourages the appearance of cracks through which corrosive agents can penetrate.
- Contamination : The presence of contaminants in the environment can accelerate corrosion. Contaminants, such as chemical compounds in the air or chemicals released in industrial processes, can interact with materials and trigger corrosive reactions.
It is important to note that the combination of several of these factors can significantly increase the speed and severity of corrosion. Therefore, it is essential to evaluate the environmental conditions and corrosive agents present in a given environment in order to implement appropriate corrosion prevention and control measures . In the next section, we will explore the places where we can find corrosion in our daily lives.
