Fig. 6: Degradation behavior and physicochemical properties of CaS.
From: A critical review of the recent advances in inclusion-triggered localized corrosion in steel
Typical secondary electron (S.E.) images and EDS mapping analysis results of CaS-contained regions in steel (a, a1–a7) before and (b, b1–b7) after immersion in 0.1 M NaCl solution for 1 h at ambient temperature. c Possible suspected structures and respective surface energy values of CaS and Fe in <1 0 0>, <1 1 0>, and <1 1 1> orientation. d Pourbaix diagram of the Fe-Ca-S-H2O systems at 298.15 K calculated by Factsage software22,67.
