| 目的 研究海洋大气环境下氯离子在Q235钢表面的沉积分布规律。方法 使用便携式X射线荧光光谱仪测试Q235钢在海南岛不同地点大气环境暴露后的表面氯离子沉积，然后采用插值算法绘制氯离子在Q235钢表面沉积分布图和海南岛不同地点氯离子在Q235钢表面平均沉积量分布图，并根据氯离子沉积分布图分析氯离子在Q235钢表面的沉积量分布规律。结果 氯离子在Q235钢表面呈不均匀分布特征。在环境暴露试验前6个月，Q235钢表面氯离子含量逐渐增加；暴露6~12个月，Q235钢表面的氯离子含量总体变化不大。从整个海南岛看，内陆地区氯离子在Q235钢表面的沉积量低，而在沿海环岛区域的沉积量高。在海南岛沿海地区，Q235钢表面氯离子沉积量随季风风向的变化而变化。结论 氯离子在Q235钢表面呈不均匀沉积分布，Q235钢表面氯离子沉积量在海南岛不同地点呈“中间低、两边高”的沉积分布规律，内陆地区沉积量低，而沿海环岛区域沉积量高，并且沿海地区的氯离子沉积易受季风风向的影响。 |

| The work aims to study the distribution law of chloride ion deposition on Q235 steel surface in marine atmospheric environment. First of all, a portable X-ray fluorescence spectrometer was used to test the chloride ion deposition on the Q235 steel surface exposed to the atmospheric environment at different places in Hainan Island, and then the interpolation algorithm was used to draw the distribution map of chloride ion deposition on the Q235 steel surface and the distribution map of the average chloride ion deposition on the Q235 steel surface at different places in Hainan Island. Finally, according to the distribution maps, the distribution law of chloride ion deposition on the Q235 steel surface was analyzed. The distribution of chloride ions on the surface of Q235 steel was uneven. In the first six months of the environmental test, the content of chloride ions on the surface of Q235 steel gradually increased, and the content of chloride ions on the surface of Q235 steel exposed for 6-12 months had little overall change. In the whole Hainan Island, the amount of chloride ions deposited on the surface of Q235 steel in the inland area was low, while the amount of chloride ions deposited in the coastal roundabout area was high. In the coastal area of Hainan Island, the chloride ion deposition on the surface of Q235 steel changed with the change of monsoon wind direction, resulting in the chloride ion deposition in different directions of Hainan Island changing with the seasons. The chloride ions are unevenly distributed on the surface of Q235 steel. The chloride ion deposition on the surface of Q235 steel at different places in Hainan Island is "low in the middle and high on both sides". The deposition in inland areas is low, while the deposition in coastal roundabout areas is high, and the chloride ion deposition in coastal areas is easily affected by monsoon wind direction. |
