| description | The influences of Mg<sup>2+</sup> and Ca<sup>2+</sup> on the short-term (1800 s) corrosion behavior of X100 pipeline steel were investigated in a sodium chloride (NaCl) solution saturated with CO<sub>2</sub>. Either Ca<sup>2+</sup> or Mg<sup>2+</sup> in the solution inhibited the short-term corrosion of X100 pipeline steel, with the corrosion current density decreasing from 262.4 μA cm<sup>−2</sup> to 163.5 μA cm<sup>−2</sup> or 80.8 μA cm<sup>−2</sup>. During longer-term (8−48 h) immersion, the Mg<sup>2+</sup> inhibited the formation of the protective scale, whereas the Ca<sup>2+</sup> accelerated the formation of the scale. Further, an experimental equation establishing the relationship between the precipitation rate of the corrosion scale and the exposure time was proposed to quantitatively study the effects of Mg<sup>2+</sup> and Ca<sup>2+</sup> on the precipitation rate of the corrosion scale. |
