Atmospheric Rust Protection
Atmospheric rust protection involves the use of temporary corrosion protection agents like oils, greases, or volatile inhibitors to protect metal parts from moisture. These layers are easily removable.
Physical-Chemical Mechanism of Action
Atmospheric rust protection is achieved by applying liquid or solid corrosion inhibitors to metal surfaces. These inhibitors form a dense layer that prevents contact between the metal and air, thus preventing the formation of corrosion products.
Metallurgical Relevance & Welding Risks
Improper application or removal of the rust Corrosion Inhibitor can lead to corrosion damage, especially when the metal is exposed to humid environments. It is important that the Corrosion Inhibitor fully covers the surface and can be easily removed to avoid contamination during welding.
Workshop Practice & Action Guidelines
Use high-quality rust inhibitors such as paraffin oil or special anti-corrosion creams. Apply the Corrosion Inhibitor in a thick layer to all metal surfaces, especially at corners and edges. Ensure the Corrosion Inhibitor can be easily removed before welding. Use a clean cloth or a chemical agent for removal.
