What is Passivation and When Passivation is Needed
Passivation is a process used to remove impurities and free iron from the surface of stainless steel, making it more resistant to corrosion. This is typically done by immersing the steel in a solution of nitric acid or citric acid. Passivation is often needed when the surface of the stainless steel has become contaminated by handling or exposure to harsh environments, and it can help to restore the material’s protective oxide layer and prevent rust and corrosion. Additionally, passivation is often used in the medical, food and aerospace industries, as it is a requirement for these industries.
Importance of Passivation and Parts Cleaning
Passivation and parts cleaning are both important processes for maintaining the integrity and performance of stainless steel parts and components. Passivation is important because it helps to remove impurities and free iron from the surface of the stainless steel, which can cause corrosion and rust if left untreated. By removing these contaminants, passivation helps to restore the material’s protective oxide layer, making it more resistant to corrosion and prolonging its lifespan.

Parts cleaning is also important because it helps to remove dirt, grease, and other contaminants from the surface of the parts, which can also cause corrosion and reduce the performance of the parts. Parts cleaning can be done using a variety of methods, such as ultrasonic cleaning, aqueous cleaning, and solvent cleaning, depending on the type of contaminants present and the intended use of the parts.
In summary, passivation and parts cleaning are both critical steps in maintaining the integrity and performance of stainless steel parts and components, and are often required in industries such as aerospace, medical and food. They help to prevent corrosion, rust and prolong the life of the parts.
