摘要: 建立实验室模拟大气腐蚀的干湿循环加速腐蚀方法.提出低碳钢锈蚀的分段演化规律,演化规律对应于锈层致密度转折和锈层结晶组分的形成,显示分段规律的合理性.实验室获得的低碳钢锈蚀演化规律与其在万宁和沈阳两个大气站现场曝晒的最新结果有相关性,证明加速腐蚀方法的可靠性.

Abstract: It has been set up an accelerated method of simulating to atmospheric corrosion by using wet/dry alternate test.The rust evolution rule of mass change vs time(in logarithmic coordinate) of low carbon steel under this test shows two linear sections with different slopes,in which the rust evolution transition in weight change corresponds to the compactness transition and crystallization transition during the rust layer growth.It has found that the rust evolution rule of low carbon steel in Wanning exposure site correlates to the rust evolution rule obtained by simulating the coastal atmospheric corrosion test,and the rust evolution rule of low carbon steel in Shenyang exposure site correlates to the rust evolution rule obtained by simulating the industrial acidic rain atmospheric corrosion test.These results proved the reliability of the simulated atmospheric corrosion accelerated test.

Key words: low carbon steel, atmospheric corrosion, simulated acceleration, rust evolution rule
