Kindly suggest the method to check the corrosion behaviour of magnesium alloys.
There are more methods to predict the corrosion behavior one of them is the weight loss per unit time.
After Dr.Suhair G. Hussein and Dr.Pierluigi Traverso
There is full agreement in all published literatures that the corrosion of magnesium and its alloys are more complex than most other metals. Therefore the test methods for determine corrosion rates can differ in their results according to many parameters. Now, if we divided these test methods for analyzing their corrosion behavior, it's possible to be either short term test method (electrochemical methods, such as potentiodynamic polarization PDP or electrochemical impedance spectroscopy EIS) or long term test methods (weight loss rate, hydrogen evolution rate, and rate of Mg2+ leaving the metal surface into test solution). In this respect, it is strongly recommended that the corrosion test by electrochemical methods should complemented by the use of at least two of the three simple long term test methods as mentioned above since deviations have been found similar to 50-90% in the obtained results from the test performed by long and short test methods.
