Abstract This paper covers a study of the stability of corrosion products on low alloy steels after leaving sea water. When taken from the sea, the samples are de-watered in alcohol, dried in cold air and coated for sealing with epoxy resin.Then the samples are packed with antirust paper and kept in a desiccator. Then the scales are taken off the steel samples in an argon cabinet and are immediately put into a test tube filled with argon. Part of the rust scale is then transferred into a sample box made of organic glass sealed leakproof and is ready for Mossbauer spectrum analysis. In this way the decomposition of extremely unstable Fe(OH)_2 can be avoided. Once the scale is exposed to the air, Fe(OH)_2 will decompose, while other physical phases will remain unchanged for a relatively long time. Any changes in physical phases will be shown from the results of Mossbauer spectrum analysis.
