Passivation Passivation is a chemical process used to treat the surface of metals and alloys to enhance corrosion resistance and improve surface properties. In laser engraving and metalworking applications, passivation involves removing contaminants, impurities, and oxides from the surface of metal components to create a passive oxide layer that protects against corrosion and rust formation.
Passivation typically involves cleaning the metal surface with acidic or alkaline solutions, followed by rinsing and drying to remove residues and restore the surface to its optimal condition. Passivation is commonly used in industries such as aerospace, automotive, and medical devices to prolong the lifespan and performance of metal parts subjected to harsh environmental conditions and corrosive agents. |
