passzíváló

Passziváló is a Hungarian term that generally refers to a passivation process or a passivation agent. Passivation is a chemical treatment of a metal surface that increases its resistance to corrosion. This is typically achieved by forming a thin, protective oxide layer on the metal. The term "passziváló" can also be used to describe the substance used to carry out this passivation, such as a passivating solution or spray.

In a more specific context, "passziváló" often relates to the passivation of stainless steel, a common application of this process. Stainless steel naturally forms a passive chromium oxide layer, but this layer can be enhanced or restored through chemical passivation. This is particularly important after machining or welding, where the protective layer may have been compromised. The passivating agent helps to remove free iron from the surface and promotes the formation of a more robust and uniform oxide film.

The effectiveness of a passiváló treatment depends on various factors, including the type of metal, the specific passivating agent used, the duration of the treatment, and the temperature. Proper cleaning of the metal surface before passivation is crucial to ensure optimal results. The treated surface exhibits improved resistance to rust and other forms of corrosion, extending the lifespan and maintaining the aesthetic appearance of the metal component. Industries that rely heavily on corrosion-resistant materials, such as food processing, medical equipment manufacturing, and aerospace, frequently employ passivation techniques using passziváló agents.
