Figure 1

SEM images showing the surface morphology of Ni–20Cr alloy corrosion in molten salts under different conditions: (a) KCl–MgCl2 in vacuum, (b) KCl–NaCl in vacuum, and (c) KCl–NaCl in air for (i) 1 h, (ii) 2 h, (iii) 4 h, and (iv) 16 h. The orange arrows indicate the facets formed on the surface after corrosion. The blue arrows indicate the cracks, the red arrows show the pores, and the yellow arrows refer to the ligaments.
