- Abstract
- In this research, the effect of calcareous deposits on the hydrogen evolution reaction and hydrogen absorption has been investigated. Therefore, the Devanathan-Stachurski cell has been used to evaluate the hydrogen uptake of a construction steel (S235) which is charged in a NaCl solution containing Ca2+ and Mg2+ under CP (Cathodic Protection) condition of -1000 mV (Ag/AgCl). On the charging side, calcareous deposits are formed on the steel surface and can influence the cathodic reaction and thus hydrogen uptake. To have a better understanding about the role of calcareous deposits on the hydrogen evolution reaction, electrochemical impedance spectroscopy is used. As such, the deposits surface coverage and resistance to hydrogen evolution reaction are measured during charging time. A NaCl solution (free of Ca2+ and Mg2+) is used as reference to avoid these calcareous deposits. Then, the cathodic current density at the charging side, the permeation current density, and hydrogen sub-surface concentration are compared. Furthermore, the deposits formed on the surface are evaluated by scanning electron microscopy and energy dispersive X-ray spectroscopy, obtaining the structure and chemical composition of the deposits. The results elucidate the mechanism of calcareous deposits influence on the hydrogen uptake.
