Dear Dr. Maamar Khalleefah Aboubakr ,

in general, you have 4 main different methods to study the corrosion behaviour of a specific material (protected or not by a coating or other surface treatments, inhibitors, etc.) in the environment of possible use:

1 - Field tests (according to standard regulations and followed by appropriate characterizations / evaluations) in a corrosive environment very similar to the one of use that require an exposure time of at least one year (or more);

2 - Salt spray chamber tests (these, too, according to standard regulations), conducted in a series of corrosive environments simulating those of real application, with often rapid assessments of a photographic type. These tests require an exposure time of about 1-2 months and are considered "accelerated tests";

3 - Lab tests in free corrosion conditions, in a controlled environment, followed by analysis of weight loss (gravimetric test)and / or morphological and chemical analyzes of the surface of the samples by scientific instrumements, for example Optical Microscopy, SEM, et. (time required about 1 month);

4 - Electrochemical measurements (eg. Potentiodynamic Polarization Curves, EIS, etc.) carried out in an suitable aggressive solution which, once the experimental parameters are optimized, are able to provide a comparative or absolute evaluation, in a time of order of one hour every single measure.

Now all that remains is to choose according to the instrumental availability you have available. Personally I prefer to use at least two of the tests mentioned above ... it is always better to have two results in agreement with each other, if time allows us to do this...
