Fig. 9: Results of gel surface chemistry in terms of weight percent of elements obtained with XPS on glass gels and compared with pristine ISG.
From: Long-term interactive corrosion between International Simple Glass and stainless steel
a) An illustration of the ISG(+SS) creviced assembly where the numbers 1, 2 and 3 represent the spots at which XPS data were acquired. For spot 1, data were collected for ISG samples corroded in NaCl as well in silica-saturated NaCl. For spots 2 and 3, the data were collected only for NaCl solution. Note that spot 3 is closer to the crevice mouth than the crevice center. b–d) The elemental composition of gel surface normalized to that of Si at regions 1, 2 and 3 in 0.6 M NaCl, respectively. e) The weight percent of Si normalized to that of Zr for gel surface at spot 1 for NaCl as well as silica saturated NaCl compared with that of uncorroded ISG.
