Abstract

Abstract

The electrochemical characteristic of ship metal materials in marine environments is an important factor affecting the generation of ship electric field characteristics. For a long time, researchers have mainly focused on the electrochemical characteristics of metal materials in normal-temperature seawater but paid less attention to the electrochemical characteristics of metal materials in low-temperature seawater. For three typical ship materials, experiments were designed based on the influence of different temperatures and salinity changes, and the polarization potential, polarization curve, and polarization resistance were compared in the low-temperature seawater. The results show that with the decrease in seawater temperature, the open circuit potential of metal materials and self-corrosion potential increase, but the degree of dissolution activation decreases. The proposed method may provide a reference for the study of electric field characteristic control and analysis and evaluation.
- low temperature seawater,
