Unilab performs corrosion tests on different materials, processes, treatments and coatings to verify the development of corrosion on the surface of the tested materials. Corrosion is a chemical or electrochemical reaction of a material with its environment which results in the degradation of the material and loss of its initial characteristics.
This phenomenon is natural and irreversible, which is why these tests, such as the salt spray chamber, allow us to determine the life cycle of components and predict their resistance.
The metal samples (with or without coating) are subjected to a comparison corrosion test (accelerated aging test) in order to obtain information about the corrosion resistance. The test results show the differences between different materials, processes, treatments and coatings (metallic and organic) on the surface corrosion development of the tested materials. We also offer the possibility of testing paints and coatings in general (coating).
Currently the specifications and requirements of these tests are increasingly present and standardized in industrial sectors such as automotive, marine, white, components and precision mechanics.
Typical accelerated aging tests provided by Unilab are:
In addition to the comparison tests, the evaluation of corrosion resistance, the laboratory of Unilab offers the possibility to carry out corrosion tests also by subjecting materials in direct contact with chemical agents under conditions of: temperature, humidity and exposure controlled and standardised with assessment of, for example, weight loss of standard samples.
This category of tests includes corrosion tests for susceptibility to pitting and intergranular corrosion in stainless steels (ASTM G48, ASTM A262).
