Alloying effect of Cr in the interaction with other elements in low alloy steel for corrosion resistance was designed and prepared. The corrosion behavior of the alloy immersed in mild acidchloride solution (200 atomic ppm Cl ¹ and pH 4) at room temperature in an ambient condition has been studied by electrochemical laboratory tests (potentiodynamic polarization test, potentiostatic test, electrochemical impedance spectroscopy) and surface analyses (SEM, XPS). The results reveal that Cr addition improved the localized corrosion resistance by promoting the formation of beneficial Fe and Cu compounds on the protective films of 0.1 and 0.3 mass% Cr steels. However, the over-alloying circumstance in 0.5 mass% Cr steel caused the negative effect of Cr addition due to metal chloride-induced hydrolysis which accelerated the propagation of the localized corrosion. To summarize, 0.3 mass% Cr addition was determined to be the optimum value for alloying to blank steel.

“…The lower the value of n, the rougher the electrode surface, and a smaller R ct value corresponds to a higher corrosion rate. The value of n is also related to the inherent physical and chemical heterogeneous nature of the solid surface [54], the presence of a porous corrosion product layer [55], non-uniform distribution of current density on the surface [56], etc. All the Nyquist plots obtained in the present study are characterized by single time constant.…”

Synergistic inhibition of corrosion of carbon steel in low chloride environment using ascorbate as a synergist along with 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTC) and Zn 2þ is presented. The synergistic effect of ascorbate has been established from the present studies. In the presence of ascorbate, lower concentrations of PBTC and Zn 2þ are sufficient in order to obtain good inhibition, thus making this formulation more environmentally friendly. Potentiodynamic polarisation studies inferred that this mixture functions as a mixed inhibitor, predominantly cathodic. Impedance studies revealed that an immersion period of 24 h is necessary for the formation of the protective film, with a very high charge transfer resistance. The film is stable even at 60 8C in the presence of the inhibitor in the corrosive environment. The surface analysis by X-ray photoelectron spectroscopy (XPS) showed the presence of iron, oxygen, phosphorus, carbon and zinc in the protective film. The XPS spectra inferred the presence of oxides/hydroxides of iron(III), Zn(OH) 2 and [Zn(II)-PBTC-ascorbate] complex in the surface film. This inference was further supported by the reflection absorption Fourier transform infrared spectrum of the surface film. A plausible mechanism of corrosion inhibition has been proposed.
