| Abstract: |
| This paper evaluates and studies the sedimentation rate and corrosion rate of chloride ions in marine environment, to provide data support for the corrosion protection of seawater pumped storage power station equipment. The sedimentation rate and corrosion rate of atmospheric chloride ions at station a far from the shore and station b near the shore in a certain area of Hainan from March to June are analyzed mainly by the dry plate method and silver test plate method From the analysis of data obtained by the dry plate method, we can see that the chloride ion sedimentation rate at station b is higher than that at station a, and its average temperature is lower than that at station a, while its average relative humidity is higher than that at station a. The analysis of data obtained by the silver plate method shows that the environment of station b is harsher, the corrosion film of station b is thicker than that of station a. The corrosion rate of the station a arrives at G2, while that of the station b reaches to G3 except for March. It is found that the variation trend of salt spray sedimentation rate obtained by dry plate method is consistent with the corrosion rate obtained by silver plate method. It can be concluded that the change of temperature and humidity is an important factor for the sedimentation rate of chloride ions, such as controlling the environment temperature and humidity, and using some salt fog purification equipment to reduce the corrosion severity of the service environment. |
