Long-term immersion test

The long-term immersion test in the context of corrosion protection is a practice-oriented method for evaluating the long-term effect of protective coatings on metallic surfaces. The aim of this test is to test the effectiveness of corrosion protection measures under realistic conditions and to evaluate the resistance of coatings to environmental influences.

During the long-term immersion test, metallic samples coated with various corrosion protection coatings are immersed in a container with a corrosive environment for an extended period of time. This environment can be, for example, salty water or a solution of aggressive chemicals, which represent typical stresses to which metallic components can be exposed in practice.

The long-term exposure of the samples makes it possible to observe the reaction of the corrosion protection coatings to the environmental influences. Any changes such as cracking, detachment or rust formation are analyzed in order to draw conclusions about the protective effect of the coatings.

The knowledge gained from the long-term immersion test is crucial for the development and selection of effective corrosion protection solutions. This practical approach enables a realistic assessment of the durability of coatings under extreme conditions and helps to prevent long-term damage to metallic components. The long-term immersion test therefore plays an important role in the quest for reliable corrosion protection in various industrial applications.
