Abstract

The corrosion behavior of SA210C steel beneath surface deposit film of mixed salts of Na₂SO₄∶NaCl = 3∶1, 1∶1 and 1∶3 in air at 600^oC was studied by means of corrosion kinetics curve measurement, as well as characterization of composition, microstructure and morphology of the corrosion products by XRD, SEM and EDS. The results show that the corrosion products on the surface of SA210C steel consists mainly of Fe₃O₄ and Fe₂O₃, and the mass gain and the thickness of corrosion products scale are positively correlated with the mass proportion of NaCl in the mixed salt film. When the mass ratio of NaCl to Na₂SO₄ in the mixed salt film is 1∶3, the corrosion products on the surface of SA210C steel have obvious cracking and delamination, and the corrosion products are seriously spalling. When the mass ratio of NaCl to Na₂SO₄ is 3∶1, penetrating cracks are observed in the corrosion products scale and internal corrosion occurs in the base metal.

Key words: SA210C steel NaCl Na₂SO₄ high temperature corrosion thermal power generation
