Inorganic Corrosion Inhibition
Inorganic corrosion inhibition blocks the corrosion process by forming poorly soluble barrier layers on metal surfaces that prevent contact with electrolytes.
Physicochemical mechanism of action
Mineral compounds react on the metal surface to form a dense layer that interrupts contact with the electrolyte. This layer prevents ion exchange and thus the formation of corrosion products.
Metallurgical relevance & risks in welding
The use of inorganic inhibitors can significantly extend the service life of metal parts by preventing corrosion damage. However, application must be done carefully, as wrong concentrations or unsuitable compounds can affect the weld and reduce strength.
Workshop practice & instructions
Use inorganic inhibitors in the prescribed concentrations. Make sure the barrier layer is fully formed by carrying out suitable post-treatment after welding. Regularly check the effectiveness of the Corrosion Inhibitor and watch for possible reactions with other materials.
