摘　　要：本文利用碳钢在我国不同海域海洋大气环境为期1年的腐蚀速率数据和不同海域大气环境的温度、湿度、氯离子沉积速率、SO_(2)沉积速率等环境因素数据,对我国渤海、东海、南海不同海域的大气腐蚀环境进行准确评级,结果表明,黄渤海和东海海域海洋大气腐蚀性等级相对较低,为C3或C4;南海海域海洋大气腐蚀性等级相对较高,为C5或CX。In this paper,the atmospheric corrosion environment of carbon steel in different sea areas of China was accurately rated based on the one-year corrosion rate data of carbon steel in different sea areas of China and environmental factors such as temperature,humidity,chloride ion deposition rate,SO_(2) deposition rate,etc.The results show that,the Marine atmospheric corrosivity in the Yellow sea,Bohai Sea and East China Sea is relatively low,which is C3 or C4.The Marine atmospheric corrosivity of the South China Sea is relatively high,which is C5 or CX.
