Localized corrosion behavior of nickel alloys in model SO/sub 2/ scrubber environments

Conference ·
OSTI ID:7244666
Nickel base alloys and austenitic stainless steels have been evaluated in a working model limestone flue gas desulfurization system previously described in the literature. Corrosion in the absorber and outlet duct zones was characterized in terms of environmental effects on localized corrosion propagation of each alloy. Increasingly environmental chloride and/or fluoride content produced a more severe environment, even in the presence of flyash. Crevice pits which initiated in 30 days, failed to propagate with additional exposure to 90 days; however, the degree of initiation increased.
