“…in the steel having a better corrosion resistance [12][13][14]. It can be seen from Table 2 that the 1# specimen with a Cu-Sb composite added to it had the lowest capacitance value and the highest Rf value, thus indicating that its resistance to electrochemical corrosion increased after low alloying [15]. Moreover, the 1# specimen with a Cu-Sb composite added to it had the best corrosion resistance performance.…”

“…The size of the impedance arc represents the ease of the charge transfer, with a larger diameter indicating a higher R f value (suggesting that the corrosion reaction is less likely to occur), which thus results in the steel having a better corrosion resistance [12][13][14].

The corrosion resistance of low-carbon steel and two new low-alloy, corrosion-resistant steels containing Cu-Sb and Cu was studied in a simulated seawater environment. The effects of Cu and Sb on corrosion resistance were analyzed by an electrochemical test and accelerated corrosion test. The results show that Cu and Sb reduce the corrosion current density by increasing the corrosion potential and increasing the polarization resistance. Sb can promote the formation of Cu-containing compounds with a strong corrosion inhibition performance, and it can enhance the overall corrosion resistance of steel. In addition, Sb can also promote the conversion of Fe2+ ions into a corrosion-resistant compound, α-FeOOH, and it also further improves the corrosion resistance of steel.

PFR combined with polymers have a wide range of industrial applications as plugging agents for pro le control and EOR. Due to the structural resemblance between lignin and phenol, there are possibilities for environmentally friendly phenol-formaldehyde resin manufacturing. SLPFR was synthesized by partially replacing phenol with lignin, which improved the utilization rate of lignin and achieved the purpose of environmental preservation and resource conservation. HPAM is the most widely used polymer in chemical methods for EOR. However, the stability of reservoirs with high salt and high temperature is weak under these conditions.To solve the problem of still low oil recovery in high-salt reservoir environments, polymer ooding is adopted, which utilises high molecular weight polymers to raise the viscosity of injected uids, thereby improving sweep e ciency and altered mobility ratio between oil and injected uid. We focus on the stability study of different molecular weight HPAM combined with SLPFR in metal ions and surfactants. The zeta potential and hydrodynamic diameter of HPAM-SLPFR system in Ca 2+ were measured by dynamic light scattering and static light scattering, and the dispersion stability was analyzed. The interfacial energy modi ed DLVO theory was introduced to evaluate the stability of its colloidal solution, which made it possible to predict the aggregation behavior of SLPFR and the comigration process of metal cations in real time.
