在六个纯海洋大气中进行了为期一年的研究，年平均氯化物沉积速率为70-1906 mg Cl-/m（2）天。本文研究了一些环境参数及其对现场气载氯化物存款的影响。本文还考虑了低碳钢的腐蚀速率和由此产生的腐蚀产物和层，以及其对现场大气盐度的依赖性。腐蚀产物中除纤铁矿和针铁矿外，还含有较高含量的赤霞铁矿和磁铁矿。由于纤铁矿的转化，可能形成额外的磁铁矿。(C)2015爱思唯尔有限公司版权所有。
Research has been carried out for one year in six pure marine atmospheres with annual average chloride deposition rates of 70-1906 mg Cl-/m(2) day. A study of some environmental parameters and their influence in the airborne chloride deposit on the site has been accomplished. The paper also considers mild steel corrosion rate and the resulting corrosion products and layers, and its dependence of atmospheric salinity of the site. In addition to lepidocrocite and goethite, high akaganeite and magnetite contents were found in the corrosion products. Additional magnetite formation is possible due to the transformation of lepidocrocite. (C) 2015 Elsevier Ltd. All rights reserved.
