Effects of Salt and Ash on high temperature corrosion behaviour of NI-25CR Alloy in Wet CO2 Gas at 650°C

ABSTRACT A model Ni-25Cr (wt.%) alloy coated with chloride salts, industrial coal ash, and mixtures of these salts with coal ash (ash/salt weight ratios: 90/10, 50/50, 25/75) was exposed in Ar-60CO2-20H2O at 650oC for 100 h and 300 h. For comparison, the alloy without any deposit was also exposed to the same gas... Read more.
