Salt spray test

The salt spray test is an important test method in the field of corrosion protection and is used to evaluate the ability of coatings and materials to withstand corrosion under aggressive environmental conditions. This test is used in various industries, especially automotive, aerospace, shipbuilding and construction.

The salt spray test simulates the effects of salty air or seawater on the surface of products or materials. This is particularly relevant for parts and components that are exposed to severe corrosion, such as vehicle body panels or marine components.

During the test, the material or product under test is exposed to a constant supply of fine salt spray, usually generated in a special chamber. This salty atmosphere creates a challenging environment for the coatings and surfaces as it accelerates corrosion.

The salt spray test makes it possible to evaluate the resistance of coatings to corrosion by identifying potential weak points or defects. During the test, visible signs of corrosion such as rusting or blistering may appear in the coating. This allows for an accurate assessment of the protective function of the coating and its durability in a corrosive environment.

The results of the salt spray test are of great importance to ensure that the coated products or materials meet the quality standards and the specific requirements for their field of application. Based on the results, adjustments can be made to the coating processes or materials to improve corrosion resistance.

Overall, salt spray testing is an indispensable tool in the field of corrosion protection and helps to ensure the longevity and reliability of products and components, especially in environments where corrosion is a significant threat.
