“…However, both passive films are structurally composed of an outer film rich in iron and molybdenum and an inner film rich in chromium, with almost the same thickness and structure [30,32] . Other literature has shown that the passive film conductivity of the austenite phase is higher than that of the ferrite phase [33] . The crystal orientation may influence the passive film, which was identified by synchrotron hard X-ray photoemission electron microscopy (HAXPEEM) [29] .…”

Duplex stainless steel is widely used in the petrochemical, maritime, and food industries. However, duplex stainless steel has the problem of corrosion failures during use. This topic has not been comprehensively and academically reviewed. These factors motivate the authors to review the developments in the corrosion research of duplex stainless steel. The review found that the primary reasons for the failure of duplex stainless steels are pitting corrosion and chloride-induced stress corrosion cracking. After being submerged in water, the evolution of the passive film on the duplex stainless steel can be loosely classified into three stages: nucleation, rapid growth, and stable growth stages. Instead of dramatic rupture, the passive film rupture process is a continuous metal oxidation process. Environmental factors scarcely affect the double-layer structure of the passive film, but they affect the film's overall thickness, oxide ratio, and defect concentration. The six mechanisms of alloying elements on pitting corrosion are summarized as stabilization, ineffective, soluble precipitates, soluble inclusions, insoluble inclusions, and wrapping mechanisms. In environments containing chlorides, ferrite undergoes pitting corrosion more easily than austenite. However, the pitting corrosion resistance reverses when sufficiently large deformation is used. The mechanisms of pitting corrosion induced by precipitates include the Cr-depletion, microgalvanic, and high-stress field theories. Chloride-induced cracks always initiate in the corrosion pits and blunt when encountering austenite. Phase boundaries are both strong hydrogen traps and rapid hydrogen diffusion pathways during hydrogen-induced stress cracking.

“…The previous literature has reported that the formation of the FeCO 3 and Cr(OH) 3 on S13Cr SS was controlled by the dissolution-precipitation process and resulted in relatively high defections (Guo et al, 2012;Zhao et al, 2019). However, the formation of the compact structures for spinel products such as Fe 3 O 4 and FeCr 2 O 4 was considered to provide better corrosion protection than that of the precipitation type (Yue et al, 2020a(Yue et al, , 2020b(Yue et al, , 2020cLiu et al, 2021). Besides, the outer corrosion products with sheet-shaped clusters characterized as a looser structure which may cause pore connectivity within the outer layer.…”

The formation and evolution of the corrosion scales on the super 13Cr stainless steel (SS) surface after exposure in a formate completion fluid with the presence of various aggressive substances was investigated. The results indicate that the formation of Fe3O4 covered the surface of super 13Cr SS as the inner layer accompanied with outer scattered FeS. The corrosion rate was below 0.07 mm/year after 120 h of exposure in the formate fluid at 180°C under N2 environments; the presence of aggressive substances such as sulfide and CO2 in the formate fluid promoted the proceeding of anodic dissolution in the early period, and the ingress of CO2 progressively increased the general corrosion rate to 1.7 mm/year. For CO2-containing conditions, the formation of FeCr2O4 and Cr(OH)3 was detected in the inner corrosion product layers, and the precipitation of “sheet”-shaped iron carbonate (FeCO3) was detected as the outer layer. The accumulation rate of corrosion products increases by two orders of magnitude with the ingress of CO2, corresponding to thicker corrosion products, but the dissolution rate is still three orders of magnitude higher than when CO2 was absent.

“…Also when the temperature was increased to 150 °C, the surface oxide film broke and the crater density was the highest. Liu 4 explored the effect of temperature on the corrosion behavior of 2205 duplex stainless steel from passivation to activation in a geothermal environment containing CO 2 . Their results show that when the test temperature is less than 150 °C, the generated film layer exhibits amorphous structural properties and contains a Ni-rich layer at the internal interface, while when the temperature is 300 °C, the generated corrosion products are nanopolycrystalline FeCr 2 O 4 , CrOOH and NiFe 2 O 4 .…”

“…With the rapid development of economic and social progress, the increasing demand for oil and gas resources has forced the development of oil and gas to the gradually harsher conditions and environment of the southwest China and the sea, so the service conditions of downhole tubing are becoming more and more severe 1 – 3 . In the field of oil and gas exploration, the increasing CO 2 content 4 and mineralization and Cl - ion content 5 , 6 in the produced fluids causes severe corrosion of ordinary carbon steel tubing 7 , even if the injection of corrosion inhibitors into the tubing column can`t effectively inhibit corrosion, carbon steel can no longer meet the long-term service requirements in harsh CO 2 corrosive environment 8 – 10 . Research workers have shifted their targets to duplex stainless steel (DSS) with better corrosion resistance.…”

Abstract2205 duplex stainless steel (DSS) has good corrosion resistance due to its typical duplex organization, but the increasingly harsh CO2-containing oil and gas environment leads to different degrees of corrosion, especially pitting corrosion, which seriously threatens the safety and reliability of oil and gas development. In this paper, the effect of temperature on the corrosion behavior of 2205 DSS in a simulated solution containing 100 g/L Cl− and saturated CO2 was investigated with immersion tests and electrochemical tests and combined with characterization techniques such as laser confocal microscopy and X-ray photoelectron spectroscopy. The results show that the average critical pitting temperature of 2205 DSS was 66.9 °C. When the temperature was higher than 66.9 °C, the pitting breakdown potential, passivation interval, and self-corrosion potential decreased, while the dimensional passivation current density increased, and the pitting sensitivity was enhanced. With a further increase in temperature, the capacitive arc radius of 2205 DSS decreased, the film resistance and charge transfer resistance gradually decreased, the carrier density of the donor and acceptor in the product film layer with n + p bipolar characteristics also increased and the inner layer of the film with Cr oxide content decreased, while the outer layer with Fe oxide content increased, the dissolution of the film layer increased, the stability decreased, and the number and pore size of pits increased.
