Establishing chloride concentration range for protective rust formation on weathering steel in simulated tropical marine atmospheres
This study determined the range of Cl − concentrations that enable the formation of protective rust layers in simulated tropical marine atmosphere by examining the corrosion of weathering steel. The steel exhibited good weatherability in atmospheres with 0.5 to 2.0 wt.% NaCl. Chloride ion influenced rust layer protection by altering phase distribution and defect structure. In the Cl-free environment, the rust layer was loose and lacked protection due to the low degree of corrosion during the limited experimental period. Excessive Cl − increased β-FeOOH content and compressed α-FeOOH distribution, raising internal stresses and compromising the protective properties of rust layer.
