Need to test the corrosion resistance of your material or a protective coating?
In collaboration with the University of Tartu we can do both chemical and electrochemical tests to simulate real or even extreme conditions in order to evaluate the performance of your sample.

Chemical tests – Studied substrates are exposed to a corrosive environment similar to the real conditions where it will be used later on. We can also alter the conditions of the environment to make it more corrosive by adjusting the pH and temperature or include UV light. A common example would be a test of series to compare the quality of stainless steel samples obtained from different suppliers. Another example would be the evaluation of different protective coatings on metal substrates.
Electrochemical tests – Corrosion can electrochemically be accelerated and this allows to quickly obtain reliable information about a materials or protective coatings corrosion resistance. For instance, certain metal alloys can be immersed in a salty water for years before it corrodes while electrochemically we can evaluate its long-term performance within a hour.
Microscopy – In addition to corrosion tests we also do microscopy studies of the tested substrates in order to get additional information about the type of corrosion. For example, Pitting corrosion often occurs undetected as it stats as a tiny hole on the surface and forms a network of tunnels inside the substrate, thus greatly degrading its mechanical properties. In contrast, uniform corrosion initially affects the aesthetic appearance of a material and mechanical properties are not much affected if the problem is dealt with.
