Fig. 5

ISG(+SS) cross-section images acquired at (a) at the crevice mouth. (b) An EDS line scan performed along the white line in (a) with the arrow pointing in the direction of the scan (c) ISG(+PTFE) cross-section image acquired at the crevice mouth. (d) ISG(+PTFE) cross section image acquired at 200 μm into the crevice mouth. (e) The variation of gel layer thickness along the distance into the ISG(+SS) crevice for both 0.6 M NaCl and silica saturated NaCl solutions at the end of t = 365 days of reaction.
