Synergistic effect of benzoate and benzotriazole on passivation of mild steel

The corrosion behavior of porous Ni3Al intermetallic materials in strong alkali solution

“…The impedance data obtained for porous Ni 3 Al can be simulated by a two ReC circuit with a Warburg resistance, in which R el was the electrolyte resistance, C ox corresponded to the double layer capacitance and R ox was the polarization resistance of the passive layer. An additional element with C ad and R ad was required to simulate the adsorption progress and Zw was a diffusion impedance [25]. For porous materials, corrosion product film formed not only on the metal surface but also on the internal surroundings of pores.…”

Corrosion inhibition of mild steel in hydrochloric acid by 6‐aminohexanoic acid

“…The semicircle Nyquist plots can be modeled by a simple ''Randles'' circuit including the ''charge transfer resistance'' (R ct ) parallel with double layer capacitance (C dl ) in series with solution resistance (R s ). The appearance of the CPE element is often related to the electrode roughness or to the inhomogeneity in the conductance or dielectric constant [14,15]. According to Fig.…”

Corrosion Inhibitors in Cooling Water Systems

“…Typically, heterocyclic inhibitors are added with other compounds for enhancing the protection of copper alloys. However, inhibition enhancement can occur, for example, with phosphonates [2] or with BTA and sodium benzoate (SB) for steel passivation [47]. Another class of inhibitors suitable for use in aqueous media comprises different carboxylates.…”
