... without going through pyrrhotite/troilite phases. In a recent study by Li et al 7 greigite was also identified as a corrosion product by XRD. The average weight loss corrosion rate was 0.14 mm/y in A15, and maximum pit depth was 62 µm. 100 80 60 A15 w/out. layer A15 wo/out. layer Mackinawite Greigite...

... is to investigate and model the electrochemical behavior of iron sulfides by specifically focusing on their cathodic characteristics in acidic solutions. Pyrite and pyrrhotite were used as the iron sulfides for these tests since they have been found when localized corrosion of steel was observed in sour pipeline...

.... The present study investigates the effect of three different experimental parameters: iron sulfide type, cathode to anode surface ratio, and salt concentration, on the galvanic coupling between steel and iron sulfides in acidic solutions. Pyrite and pyrrhotite were selected as iron sulfide specimens since...
