Abstract
The inhibition effect of sodium molybdate (Na2MoO4) at concentrations of 50, 100 and 200ppm in 60°C on the electrochemical corrosion behavior of 316L stainless steel in LiBr solution at 60°C was studied by polarization curves, electrochemical impedance spectroscopy (EIS) methods and electron microscopy. Polarisation curves indicate that Na2MoO4 acts as mixed-type inhibitor. The corrosion resistance of 316L stainless steel samples increases with the inhibitor concentration up to 200ppm. By increasing the inhibitor concentration from 50ppm to 200ppm, corrosion current density decreases. This result was confirmed by scanning electron microscopy. Figure 1
