Corrosion

Corrosion - Environment Simulation

Metal samples with or without coating are subjected to corrosion tests using the physical simulation of highly corrosive environments in order to obtain information related to "corrosion resistance". The tests show the differences that different materials, processes, treatments and coatings have on the development of corrosion on the surface of the tested materials. rooms available for this type of test.
