Korróziógátló

Korróziógátló refers to a substance or treatment that inhibits or prevents corrosion, the degradation of a material, typically a metal, due to chemical or electrochemical reactions with its environment. These substances work by forming a protective barrier on the surface of the material, altering the surface chemistry to make it less reactive, or by scavenging corrosive agents from the environment.

Common types of korróziógátló include organic inhibitors, inorganic inhibitors, and volatile corrosion inhibitors (VCIs). Organic inhibitors, such as amines and carboxylic acids, often adsorb onto the metal surface, creating a physical barrier. Inorganic inhibitors, like chromates and phosphates, can form passive oxide layers or react with the surface to reduce its electrochemical potential. VCIs are compounds that slowly evaporate and create a protective vapor phase, effective in enclosed spaces.

The application of korróziógátló is widespread across various industries. They are used in manufacturing processes, such as metal plating and pickling, to protect goods during transit and storage. In the automotive industry, they are incorporated into coolants, lubricants, and paints to prevent rust and degradation. The oil and gas industry utilizes korróziógátló in pipelines and drilling equipment, while the construction sector employs them in concrete admixtures and protective coatings for steel structures. Effective use of korróziógátló is crucial for extending the lifespan of materials and equipment, ensuring safety, and reducing maintenance costs.
