What is passivation?

Passivation is a chemical process that is used to prevent corrosion in metals. It involves the creation of a protective oxide layer on the surface of the metal, which acts as a barrier to prevent corrosion from occurring.

Passivation is commonly used on stainless steel and other types of metals that are prone to corrosion. The process typically involves cleaning the metal surface to remove any contaminants, followed by immersion in an acid solution or the application of a passivation coating to promote oxide formation.

Passivation is an important step in the manufacturing and maintenance of metal components, as it helps to extend the lifespan of the material and maintain its appearance. It is often used in industries such as aerospace, automotive, and medical devices, where corrosion resistance is critical.

Overall, passivation is an effective method for protecting metals from corrosion and ensuring their longevity and performance.
