nitric and citric passivation
Passivation is the removal of contaminants from the surface grain boundaries of metals such as stainless steel to allow the growth of a natural, inert, oxide layer on the metal.
Customers rely on NEE for precise and consistent finish, from one part to 100,000.

Understanding Chemical Passivation
Passivation is the removal of contaminants from the surface grain boundaries of metals such as stainless steel to allow the growth of a natural, inert, oxide layer on the metal. Contaminants such as sulfides (used in manufacturing processes) and free iron inhibit the formation of the oxide layer that protects metals like stainless steel from corrosion. In chemical passivation, such as nitric passivation or citric passivation, acid immersion is used to remove contaminants. When contaminants such as free iron are removed from the metal’s surface, they can no longer react with the atmosphere to form rust.
