we used ionic strength to describe the influence of fluid composition on theν1-CO32−Raman line. According to the Debye-Hückel theory of electrolytes, the total ionic strength (I) of a given aqueous
Figure 5 shows the equivalent circuit diagram of the Al0.8CrFeCoNiCu0.5B0.1 coating for EIS. The equivalent circuit includes solution resistance, charge transfer resistance, and double-layer capacitance at the interface between the electrode and the solution. The formation of the double-layer capacita...
