Effects of various accelerated corrosion conditions on corrosion behavior of galvanized steel in marine atmospheric environment (full paper)

Galvanized steel,Electrochemical test,Microstructure,Corrosion behavior

In this work, the salt spray test and applied current accelerated corrosion test were used to simulate the accelerated corrosion process of the ocean atmosphere. The electrochemical tests were conducted to study the effect of different concentrations of NaCl solution (3.5%, 5% and 10%) and immersion time (0, 24, 48 and 96 h) on the corrosion behavior of galvanized steel in marine atmospheric environment, and a variety of analysis methods were used to study the corrosion behavior of galvanized steel in the simulated ocean atmosphere. The effects of static immersion test with various concentrations of NaCl solution on the corrosion behavior of galvanized steel in marine atmospheric environment were further studied. In addition, this work can guide and evaluate the service life of transmission towers.
