Elektrokorációval

Elektrokorációval, a Hungarian term, translates to "with electro-corrosion" or "electro-corrosion" itself in English. This refers to the process of corrosion that is driven or accelerated by electrochemical reactions. In essence, it describes the degradation of a material, typically a metal, due to the flow of electrical current within an electrolyte.

This phenomenon is fundamentally an electrochemical process where anodic and cathodic sites exist on the surface of the metal. At the anode, the metal oxidizes, losing electrons and forming ions, which is the essence of corrosion. At the cathode, a reduction reaction occurs, often involving oxygen or hydrogen ions from the surrounding environment. The electrolyte, which can be water, soil, or even atmospheric moisture, acts as the medium for ion transport between the anodic and cathodic areas, completing the electrical circuit.

Elektrokorációval can manifest in various forms, including galvanic corrosion, where two dissimilar metals are in electrical contact within an electrolyte, leading to accelerated corrosion of the more active metal. It is also a key factor in stray current corrosion, where unintended electrical currents from sources like welding, cathodic protection systems, or electrical railways can induce corrosion on buried or submerged metallic structures. Understanding and mitigating elektrokorációval is crucial in many industrial applications, particularly in the protection of pipelines, bridges, and marine structures against premature failure.
