Corrosion
Corrosion occurs when a material reacts with its environment. The component or system can be significantly impaired in its function. Passive corrosion protection prevents contact between the material and its environment through shielding. Complete separation from the environment and the corrosive material is not necessary in active corrosion protection.
Examples of passive corrosion protection
- Hot-dip galvanizing
- Protective coating or paint with appropriate pre-treatment or adhesion promoter
- Organic transport protection such as greases, waxes, or fluorinated polyurethane
- Inorganic non-metallic protection such as glass, oxides, or passivation
- Inorganic metallic protection such as zinc, aluminum, or hematite
- Constructional measures during welding, such as continuous, double-sided, and all-around welding
- Cavity sealing/conservation
- Installing water drains at vulnerable points, such as car doors
- Avoid direct contact between dissimilar metals, such as mounting chrome or aluminum parts directly on steel
- Gas-filled relays, reed relays
- Electrolytic nickel plating, galvanizing, palladizing, gold plating, etc.
- Overpressure ventilation and air filtration, e.g., in housings and control cabinets using chemisorptive filters to remove corrosive gases
Examples of active corrosion protection
- Hot-dip galvanizing
- Sacrificial anode
- Thermal spraying
- Impressed current anode
- Zinc flake coating
- Cathodic corrosion protection
- Polarization
- Inhibitors
- Reducing oxygen content
- Promoting passive layer formation
- Homogenizing the microstructure
- Optimizing the surface
Hot-dip galvanizing protects steel both passively and actively from corrosion. The zinc layer physically separates the steel from the environment and forms a so-called patina, which significantly slows down the corrosion of the zinc. In addition to this passive corrosion protection, zinc is chemically less noble than iron, donates electrons, and dissolves. The more noble element, steel, remains intact. In this common redox reaction, the zinc layer "sacrifices" itself for the underlying steel component.
