MECHANISM OF INDUSTRIAL ATMOSPHERIC CORROSION FOR CARBON STEEL

Accelerated corrosion tests in simulating industrial environments obtained by decomposition of NaHSO3 were conducted.Corrosion products were analyzed by IR,XRD and SEM;Corrosion rate was measured.The forming mechanism of α-FeOOH、δ-FeOOH and Fe3O4 in the rust was put forward.
