Corrosion is a gradual process of metal degradation caused by environmental factors such as water, oxygen, salts, or chemicals. It is a chemical or electrochemical reaction that leads to the breakdown of the metal’s structure and the loss of its mechanical and aesthetic properties. Corrosion is a significant issue in industries, especially in sectors like construction, energy, transportation, and machinery production.
Chemical corrosion occurs as a result of a reaction between metal and chemical agents, such as gases or liquids. An example is the oxidation of metals in the presence of aggressive gases like chlorine or hydrogen sulfide.
Electrochemical corrosion is a process where chemical reactions are accelerated by the flow of electrical current. A typical example is the rusting of iron in the presence of water and oxygen, where a galvanic cell is formed.
Atmospheric corrosion results from the interaction of metals with environmental factors such as humidity, rain, or acid rain. This is the most common form of corrosion, especially in urban and industrial settings.
Localized corrosion includes forms such as pitting, intergranular, or stress corrosion. It is particularly dangerous because it focuses on small areas, leading to rapid structural weakening of the metal.
Using protective coatings, such as powder coating, galvanization, or anodization, reduces the metal's exposure to corrosive factors. These coatings form a barrier that shields the metal’s surface from moisture, salts, and chemicals. The effectiveness of these coatings depends on their thickness and uniformity.
Corrosion-resistant materials, such as stainless steel or aluminum alloys, are widely used in environments prone to corrosive exposure. Stainless steel contains chromium, which forms a passive oxide layer on the surface, protecting it from further degradation. These alloys are particularly recommended in high-humidity or saline environments, such as the marine industry.
Cathodic protection involves using an anode made of a material more prone to corrosion, such as zinc or magnesium. This process creates an electrochemical cell where the anode undergoes controlled corrosion, protecting the primary metal (the cathode). This method is particularly effective in protecting underground structures, such as pipelines, and in aquatic environments, such as ship hulls.
Inhibitors are chemical substances introduced into the corrosive environment to slow or prevent corrosion reactions. They work in various ways, such as forming an invisible protective layer on the metal’s surface or neutralizing aggressive chemical compounds. They are widely used in the oil and chemical industries, as well as in cooling towers and refrigeration systems.
At Pro Metal Form, a company specializing in metal processing and welding services, corrosion is a critical factor to consider in technological processes. The use of advanced technologies, such as TIG and MAG welding or robotic welding, minimizes the impact of corrosion on finished products. The company also employs protective techniques, such as powder coating and galvanization, to ensure the durability and quality of its products.
Metal corrosion is a complex process that affects the durability and quality of metal structures. By applying appropriate protection methods and modern technologies, such as those used by Pro Metal Form, it is possible to effectively prevent metal degradation. Awareness of the risks and the implementation of protective solutions are key to ensuring durability and safety in industrial applications.
