Abstract

Using pitting corrosion, crevice corrosion and salt-spray tests, the corrosion behavior of 904L stainless steel samples with the surfaces uncoated, half-coated and full-coated with EB104/EB202 was investigated in FeCl₃ solution with different FeCl₃ concentrations. The results show that the corrosion degree of the EB104/EB202 uncoated samples became worse with the increase of FeCl₃ concentration both in pitting corrosion and in crevice corrosion. For the EB104/EB202 half-coated samples, the corrosion degree declined in the crevice zone, uncoated zone and full-coated zone in sequence. Pitting and crevice corrosion appeared together in the crevice zone, and the corrosion degree of the half-coated samples also became worse with the increase of FeCl₃ concentration. The EB104/EB202 full-coated samples exhibited good resistance to pitting corrosion, crevice corrosion and salt-spray corrosion.
