Passivation - Passivation is a chemical treatment process that enhances the corrosion resistance of metal surfaces, primarily stainless steel and aluminum. It involves removing free iron and other contaminants to create a uniform, protective oxide layer on the metal surface. *. Purpose of Passivation 1. Corrosion Resistance: Strengthens the natural oxide layer to protect against environmental damage. 2. Cleanliness: Removes contaminants, such as iron particles, from the surface. 3. Improved Durability: Extends the lifespan of the material by reducing susceptibility to rust and oxidation. #Passivation Manufacturer. * Metals Suitable for Passivation 1. Stainless Steel: Grades like 304, 316, and others benefit significantly from passivation. 2. Aluminum: Often passivated to enhance its naturally occurring oxide layer. 3. Titanium: Improves resistance to aggressive chemical environments.
