Corrosion Behavior of Galvanized Steel in Different Simulated Service Environments

The corrosion behaviors of galvanized steel in simulated marine, industrial and marine industrial environments were investigated by polarization curve measurements. The results show that in simulated marine environment, the corrosion rate of galvanized steel first increases and then decreases with the increase of Cl- ions concentration. In simulated industrial environment, as the concentration of HSO3- increases, the corrosion rate of galvanized steel increases. In simulated marine industrial environment, the corrosion rate increases with the increases of concentration of Cl- and HSO3-.
