The Inhibition Effect of Sodium Glutarate towards Carbon Steel Corrosion in Neutral Aqueous Solutions

Figure 8

High resolution C 1s spectra for native oxide film on carbon steel (a, b) and for carbon steel sample after 2 h immersion in 0.02 M NaCl solution containing 0.1 M sodium glutarate (c, d). In each case, results for two different takeoff angles (0° and 50°) are presented.
