“…However, after the addition of chlorides, the FeCr2O4 oxidation peak was higher in the 2205 bars due to the heavy pitting observed around the bars. These findings are also consistent with those from other authors [31]- [33], [59]- [61], [66] who observed Mo to be beneficial in the ferritic phases of the duplex alloys.…”

“…These findings support other authors' observation [31]- [33], [59]- [61], [66] that the influence of Mo in austenitic phase diminishes with pH. On the other hand, both the corrosion current densities of the Mo-containing 2205 grades and the intensity of the peak attributed to the FeCr2O4 oxidation are lower than those of the Mo-free 2304 grades.…”

The vulnerability of concrete reinforcing steels to corrosion when depassivation occurs, typically in the presence of chloride, makes it important to understand the nature of the steels' passive films. In the Part I of the study, electrochemical techniques and Mott-Schottky analysis were used to investigate these films formed on five different grades of stainless steel and carbon steel reinforcing bars exposed to simulated concrete pore solution. The influence of the steel composition and surface finish on Mott-Schottky plots and the electronic properties are discussed in relation to the steels' corrosion resistance. A p-type semiconductor behaviour was observed in the stainless steel alloys in the cathodic potential regions and an n-type in the anodic potential regions. The n-type behaviour is similar to that observed in the carbon steel.

Three products are synthesized by adjusting current density and quantity of ionic liquid [Bmim][PF6] in electrochemical oxidation of piperazine. The molecular structures of N-methoxyl piperazine, Ncarbonyl piperazine and N, N'-dicarbonyl piperazine are determined by infrared spectroscopy and gas chromatography (GC)/mass spectrometry (MS). For application, the inhibition effect of the three products on the corrosion of HP13Cr steel in 20% (weight %) HCl solution was studied by means of weight loss and polarization measurements. The experiments revealed that N-carbonyl piperazine and N, N'-dicarbonyl piperazine show 91.0% and 95.2% inhibition efficiencies respectively at the concentration of 3% (weight %). However, the product of N-methoxyl piperazine has no inhibition behavior.
