摘　　要：通过碳钢在自然海水和灭菌海水两种介质中的7 d暴露试验,比较了碳钢在自然海水和灭菌海水中腐蚀行为和腐蚀机理的差异。结果表明,微生物是影响碳钢腐蚀的重要因素,它影响到碳钢的腐蚀机理,同时会加重碳钢的局部腐蚀。Exposure test of carbon steel was carried out in natural seawater and sterile seawater for 7 d 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.

关 键 词：碳钢 自然海水 灭菌海水 机理
