| 摘 要： | 通过对17种碳钢和低合金钢在重庆地区江津试验站和海南万宁试验站进行16年的长期暴露试验,得到各种钢在重庆和万宁地区的大气腐蚀长期变化规律。指出在江津地区,碳钢和低合金钢可以用4年的短期大气腐蚀数据预测长期大气腐蚀规律。在万宁地区初期腐蚀率较低,但一定时间后腐蚀率呈上升趋势,耐候钢的腐蚀可以采用短期腐蚀数据预测长期结果,对于其他钢种则不能用短期数据预测长期腐蚀情况。对于江津地区,工程上选材可主要考虑经济因素。在万宁地区,工程上选材应重点考虑材料性能的差异。

| Abstract: | Long-term atmospheric corrosion rule of 17 kinds of carbon steels and low alloy steels after 16 years outdoor exposure test at Jiangjin sit located in Chongqing and Wangning site located in Hainan was analyzed.Results showed that the long-term atmospheric corrosion rule of carbon steel and low alloy steel in Jiangjin can be forecasted through 4 yeas atmospheric corrosion data.Lower initial corrosion rate of steels was found in Wanning,but rose after a certain period of time.The long-term atmospheric corrosion rate of weathering steels in Wanning can be forecasted through short-term atmospheric corrosion data,but other kinds of has no such rule. |
