Passivation is a chemical process designed to enhance the corrosion resistance of metals, particularly stainless steel. During passivation, a thin layer of oxide is formed on the metal surface, creating a protective barrier against corrosion and other environmental factors. This process removes any impurities or contaminants from the metal, promoting the formation of a passive, non-reactive surface. Passivation is commonly used in industries such as manufacturing, aerospace and healthcare to improve the longevity and performance of metal components by preventing corrosion and preserving their integrity.
