研究被执行以便在在沈阳城市的空气暴露的碳钢的锈层上调查沾染物和气象学的变量的效果。七种沾染物和 12 种气象学的参数也被登记以便相关关于腐蚀率和逐步的多重回归分析的数据被执行以便获得最好的回归模型。象阳光时间和 H 2 S 能刺激碳钢的起始的大气的腐蚀。碳钢的起始的大气的腐蚀动力学被观察跟随立方的方程。腐蚀产品被 XRD 分析,在不同时期的阶段的转变被讨论。
A study was carried out in order to investigate the effect of contaminants and meteorological variables on the rust layer of carbon steel exposed in Shenyang urban atmosphere. Seven kinds of contaminants and twelve kinds of meteorological parameters were also registered in order to correlate the data with respect to corrosion rate and the stepwise multiple regression analysis was carried out in order to obtain the best regression model. The sum of rainfall time as well as sunshine time and the concentration of H2S could stimulate initial atmospheric corrosion of carbon steel. The initial atmospheric corrosion kinetics of carbon steel was observed to follow the cubic equation. The corrosion products were analyzed by XRD and the transformation of phases in different periods was discussed.
