“…As can be seen from Figure 4 (a1), the brass surface was covered with loose corrosion products after five days immersion in SCW. According to the EDS results ( Figure 4 (a2)), the corrosion products were mainly composed of C, O and Zn, which should be the zinc compound Zn 5 (CO 3 ) 2 (OH) 6 [ 17 ]. The surface morphology of brass in SCW-SDBS is shown in Figure 4 (b1).…”

“…In addition, 4.39% of the Al element was also detected, indicating the existence of small amounts of Al 2 O 3 nanoparticles mixed with the SDBS adsorption film. Comparing Figure 4 (b1) and Figure 4 (d1), it can be found that the adsorption film of SDBS on the brass surface was relatively dense and uniform in the SCW-SDBS-Al 2 O 3 nanofluid, making the corrosion resistance of brass in this nanofluid better than that in the SCW-SDBS medium [ 17 ].…”

“…Furthermore, the positively charged Al 2 O 3 nanoparticles could be adsorbed on the negatively charged SDBS film, improving the protection performance of the SDBS film on brass [ 32 ]. In addition, Al 2 O 3 nanoparticles can also improve the critical micelle concentration of SDBS [ 17 ], therefore the SDBS adsorption film was not easy to aggregate on the brass surface. Therefore, brass has the best corrosion resistance in the SCW-SDBS-Al 2 O 3 nanofluid among the four test media.…”

“…The piperine surfactants which were synthesized by Tantawy et al [ 16 ] can be chemically adsorbed on the steel surface, and have a corrosion inhibition effect on C1018 steel in a 3.5% NaCl solution. Sodium dodecyl benzene sulfonate (SDBS) is a common surfactant used in nanofluids, and it also exhibits a corrosion inhibition effect on metals at appropriate concentrations [ 17 ].…”

The corrosion behavior of brass in TiO2 and Al2O3 nanofluids using a simulated cooling water (SCW) as the base solution and sodium dodecyl benzene sulfonate (SDBS) as the dispersant was studied by electrochemical measurements and surface analysis in this paper. It was found that SDBS could be adsorbed on the brass surface to form a protective film and have a corrosion inhibition effect on brass in SCW. In the SCW-SDBS-TiO2 nanofluid, some negatively charged TiO2 nanoparticles were attached to the brass surface and no obvious SDBS adsorption film was found, and the SDBS in this nanofluid had almost no corrosion inhibition on brass. In the SCW-SDBS-Al2O3 nanofluid, the brass surface was covered by a uniformly distributed SDBS film containing some Al2O3 nanoparticles which were positively charged, and the corrosion inhibition of brass was significantly improved in this nanofluid. It is concluded that the adsorption of SDBS on the brass surface in nanofluids is related to the charge status of the nanoparticles, which makes brass have different corrosion resistance in various nanofluids.

Rationale This work presents the first surface analysis investigation of 2‐phenylimidazole (PhI) as a corrosion inhibitor for brass in a 3 wt.% NaCl solution using time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS) and X‐ray photoelectron spectroscopy (XPS). Methods A time‐of‐flight secondary ion mass spectrometer was used to describe the elemental and molecular specific signals on the brass surface. Gas cluster/monoatomic ion beam depth profiling and two‐dimensional (2D) imaging showed the surface properties of the PhI surface layer. In addition, detailed XPS was used to describe the element‐specific signals on the brass surface. Furthermore, principal component analysis demonstrated the distribution of the different phases of the surface. Finally, the applicability of PhI in hot corrosion studies was suggested by a thermal stability experiment. Results TOF‐SIMS measurements showed an intense positive‐ion TOF‐SIMS signal for protonated PhI, i.e. C9H9N2+ at m/z 145.07. Moreover, there was an intense negative‐ion TOF‐SIMS signal for deprotonated PhI, i.e. C9H7N2¯ at m/z 143.06. Gas cluster ion beam sputtering associated with the analysis of the XPS‐excited Cu L3M4,5M4,5 revealed a connection between Cu(I) and PhI to form organometallic complexes. Conclusions The formation of the organometallic complexes with Cu and Zn metal atoms/ions was identified using TOF‐SIMS in positive and negative polarity mode: PhI–Cu, PhI–Cu2, PhI–Zn, and PhI–Zn2 complexes were present on the brass surface. The TOF‐SIMS measurements were supported by XPS measurements.

Corrosion is a significant issue for metals and alloys items because it critically affects their lifetimes. To protect the metal from corrosion, corrosion inhibitors can be added into coatings, but the inhibitor can leach into the environment. Polymer‐corrosion inhibitor conjugates are developed to solve this problem. However, corrosion can occur in various fields of applications, which then need a different level and type of metal's protection. β‐thiopropionate and ester linkages between polymer and inhibitor are selected as model for very labile and moderately labile linkages, respectively. The rate of inhibitor's release is controlled by the linkage of conjugated payloads. Corrosion measurements indicated that polymers with the β‐thiopropionate linkage are suitable for severe corrosion and short‐term applications, whereas the polymers with ester linkage can be used for mild corrosion and long‐term applications.
