Corrosion Preservation
Corrosion protection preservation protects metals from rusting through temporary layers of oils, greases, or waxes. These layers prevent contact with moisture and pollutants.
Physicochemical Mechanism of Action
Corrosion protection preservation refers to the application of liquids or solids to protect metal surfaces from corrosion. These layers form a barrier between the metal and the environment, preventing direct contact with humidity and chemical pollutants that cause rusting.
Metallurgical Relevance & Welding Risks
Incorrect application or use of inadequate preservation products can lead to corrosion under the layer. This can cause cracks and loss of strength during processing or later use of the metal. Additionally, if the layer is not completely removed before welding, it can worsen the weld seam.
Workshop Practice & Action Instructions
Use high-quality preservation oils or waxes with a stable addition of noble metals like silver. Apply a thin layer to the metal surfaces and let dry. Avoid over-application, as too much material can leave heavy residues. When machining or welding, thoroughly remove the preservation layer by cleaning and polishing.
