碳钢广泛应用于海水环境中，研究环境因素对碳钢海水腐蚀的影响有重要意义。采用海水暴露试验、流动海水腐蚀、生物污损观察和微生物数量测试方法，研究了在碳钢暴露初期环境因素对腐蚀速率的影响。结果表明，在海水暴露初期，温度、流速是影响碳钢海水腐蚀速度的主要因素，溶解氧浓度的影响被温度影响掩盖，大型生物污损影响较小，而微生物对腐蚀产生的影响逐渐显现。

Carbon steels are widely used in seawater, so the research of the effects of environment factors on corrosion rate of carbon steels is of great importance. By the method of exposure tests in seawater and flowing seawater, biofouling observation and microorganism test, the effects of environment factors on corrosion rate of a carbon steel at the early stage were discussed. It turned out that temperature and flow velocity were the main factors at the early stage and the effect of dissolved oxygen concentration was concealed by the effect of temperature, meanwhile, larger organisms were the minor factors and microorganism began to have an important influence on corrosion of carbon steel.
