Abstract:
      Exposure test of carbon steel was carriedout in natural seawater and sterile seawater for7d and the difference of corrosion behavior and mechanism in the two mediums were compared. The result showed that microorganism is an important influencing factor of carbon steel corrosion, which effects the corrosion mechanism and aggravates carbon steel local corrosion.
