【Abstract】 This paper mainly discussed corrosion of A3 steel in seabed sediment (SBS)environment. Many facilities such as underwater oil gas pipelines, oil platform etc. are damaged in SBS zone. electrochemical measurements included potentiodynamical scanning measurement and electrochemical impendence spectroscopy were performed in three kinds SBS with different granularities. Corrosion rate and other electrochemical factors were acquired, and the corrosion mechanism was also discussed.更多还原
