“…The reciprocal of R p is proportional to corrosion rate. At a higher nitrogen content, the R p value was larger, indicating a higher protective ability of passive film and a lower corrosion rate [49]. It is in accordance with the results conducted by Wu [50] et al that the addition of N improved the stability of passive film and thus enhanced passivation of austenite steel.…”

A series of electrochemical tests combined with scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and X-ray photoelectron spectroscopy (XPS) were used to study the effect of nitrogen content on the composition and structure of passive film of a high nitrogen austenitic stainless steel (HNSS) in 0.5 mol/L sodium chloride solution and its corrosion performance. The results showed that the proportion of low-angle grain boundaries in the HNSS increased with the increase of nitrogen content. Electrochemical results suggested that the HNSS with a higher nitrogen content had a lower corrosion current density in 0.5 mol/L NaCl solution and thus a lower corrosion rate. This was attributable to the formation of higher proportion of stable oxides (i.e., Cr2O3) in the passive film, accelerating the passivation process and promoting the corrosion resistance.

“…The concentration of ions at the interface was much higher than that in the UT specimen, which increased the nucleation rate ( V N ) for the formation of a whole oxide film. V N can be calculated by equation (1) (Feng et al , 2022): where A is a temperature-dependent constant, σ is the supersaturation, υ 0 is the molecular volume, γ is the surface energy of critical nucleation size, k is the Boltzmann constant and T is the temperature. After the formation of ultrafine grain layer, γ decreased and σ increased.…”

“…Nickel-based alloys have been extensively used for manufacturing steam generator tubes in pressurized water reactor (PWR) nuclear power plants due to their outstanding corrosion resistance in high temperature water. However, stress corrosion cracking (SCC) of the alloys was reported (Cheng and Zuo, 2018;Hou et al, 2011), and the sensitive microstructure and the tensile stress applied to the alloys were the dominant factors for the occurrence of SCC (Chen et al, 2021;Gonzalez-Rodriguez et al, 2021).…”

Purpose This paper aims to understand the effect of water jet cavitation peening (WJP) on stress corrosion cracking (SCC) behavior of alloy 600 and alloy 182 in high temperature water. Design/methodology/approach Surface and cross-section morphology, grain boundary microstructure, residual stress and strain distribution, hardness and surface roughness in water jet cavitation peened alloy 600 and alloy 182 were characterized. Findings A superior stress corrosion cracking resistance was obtained in 600MA, which can be attributed to the formation of the ultrafine grain layer and the higher magnitude residual compressive stress. Originality/value Relationship between WJP-induced microstructure and stress state change and SCC susceptibility was conducted. It could provide a theoretical basis for developing application of WJP in nuclear power plants.

“…Due to the high alkali solution (pH ≈ 12.5) in the small pores of cement, a dense passive film is formed on the casing steel surface. This formation contributes to excellent corrosion resistance of the casing [1][2][3][4][5]. However, in a complex underground environment, with higher temperature and pressure than on the ground and exposure to different media, and with time or cracking of the cement, water and chloride ions from outside penetrate the cement sheath and reach the interface between the cement sheath and the casing steel.…”

In the petroleum industry, the casing steel is fixed with a cement sheath to ensure reliable service in demanding conditions characterized by high temperature, high pressure, and exposure to multiple types of media. After the hydration of the cement, a porous material is produced with a highly alkaline solution filling the pores, commonly referred to as the pore solution. The casing will form a protective passive film when in contact with a highly alkaline pore solution. Nevertheless, once the cement sheath cracks, chloride ions in the stratum will pass through the cement sheath to the surface of the casing. When chloride ions accumulate to a certain concentration, the passive film will be destroyed, without exerting a protective influence on the substrate. After chloride ions come into direct contact with the casing, the casing is prone to severe failure due to corrosion perforation. The casing failure can cause a blowout outside the casing and even scrapping of the oil well. Controlling casing corrosion and ensuring casing integrity relies on understanding the critical chloride ion concentration that can cause the degradation of the passive film. Therefore, to assess the electrochemical properties and analyze the damage process of the passive film under varying chloride ion concentrations, several characterization techniques were employed. These included potential–time curves (E-t), polarization curves, electrochemical impedance spectroscopy (EIS), and Mott–Schottky curves. In addition, the composition of the passive film on the surface of the P110 casing steel was qualitatively analyzed using X-ray photoelectron spectroscopy (XPS). To further understand the surface morphology of the P110 casing steel, scanning electron microscopy (SEM) was used.
