摘要

结果表明，NaCl溶液液滴对铁的腐蚀速率大于浸泡对铁的腐蚀速率，且随盐度的升高和温度的降低而增大。随着温度的降低，液滴的润湿性增加，液滴界面表面氯离子过剩增加。更薄的液滴显著加速了溶解氧的还原反应，导致每个溶液接触面积的腐蚀速率更高。

Atmospheric corrosion rate of iron with high salinity solution droplets at low temperatures

The corrosion rate of iron with NaCl solution droplets was found to be greater than that by immersion in the solution, which increased not only with increasing salinity but also with falling temperature. As the temperature fell, the wettability of droplets increased and the surface excess of chloride ions at the droplet interface increased. Thinner droplets significantly accelerated the reduction reaction of dissolved oxygen, resulting in a higher corrosion rate per solution contacting area.

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
