“…4. The voltage and current have both increased in value until they have reached their highest peak without being inhibited, as seen by the curve of polarization [30,33]. With the inhibitor, there was noticeably less cathodic and anodic current density as well.…”

The examination of the inhibitory rates of Piper cubeba official extract (P. cubebaOE) on C-steel in 1.0 M H2NSO3H solution is covered in the research article. Utilizing chemical and electrochemical methods in addition to theoretical calculations such as DFT, Fukui function, the study produced results that indicated up to 96.0% inhibition at 300 ppm at 25oC., P. cubebaOE is an inhibitor of mixed kind. Through increasing concentration, Nquist diagrams showed that the charge transfer resistance elevated and the capacitance of the double layer decreased. It was also discovered that the inhibition process follows the Langmuir isotherm, demonstrating the generation of a monolayer on the surface of the C-steel.

“…Consequently, the overall corrosion of the alloy under flowing conditions was drastically diminished. 131 In a similar study, 61 the impact of adding rare earth alloying elements, such as cerium (Ce), samarium (Sm), and ytterbium (Yb) on the cavitation erosion characteristics of a NAB alloy was evaluated. The addition of these rare earth elements was found to significantly reduce the size of κ I and κ II phases, leading to a decrease in the boundary density of α/κ.…”

“…112 Similarly, increased levels of Ni were found to be beneficial for enhancing the corrosion resistance of NAB under flowing conditions. 131 Metallurgically, this chemical adjustment decreased the phase fraction of a and b 0 , resulting in a decrease in the cathodic reaction of O 2 reduction. The lower amount of corrosion-sensitive b 0 also reduced the anodic reaction.…”

“…When the Al content increases, the content of high-strength κ II and κ III increases, and the content of high-plasticity matrix α decreases. As the Ni content increases, the solid solubility of Ni atoms in the matrix α increases, which can enhance solid solution strengthening [ 10 ]. In the corrosion process, Ni can promote the growth of the surface oxide film and inhibit the formation of corrosion-prone β′, leading to the static corrosion resistance rising and the electrode potential and polarization resistance increasing.…”

To study the effect of aluminum and nickel elements on the microstructures and properties of the nickel–aluminum bronze (NAB) alloy, four kinds of alloys with different compositions, ZCuAl7–7–4–2, ZCuAl8-6-4-2, ZCuAl9-5-4-2, and ZCuAl10-4-4-2, are prepared by vacuum-melting technology. The effects of different Al/Ni ratios on the microstructures of NAB are investigated using a metalloscope, scanning electron microscopy, transmission electron microscopy, and XPS analysis. The mechanical property is evaluated with microhardness testing and tensile mechanical testing. The corrosion resistance is evaluated using mass-loss testing, electrochemical testing, and corrosion-product characterization. The results show that with the increase of the Al/Ni ratio, the content of precipitated phases increases, while β′ and hard κ, which have a different morphology, appear. As the Al/Ni ratio rises from 1 to 2.5, the hardness increases from 104 HV to 202 HV, and the tensile strength increases by 394 MPa from 356 MPa to 751 MPa, but the elongation decreases substantially from 50.50% to 11.00%. The best corrosion resistance is shown on ZCuAl7-7-4-2, with a corrosion rate of 0.00267 mm/a after 30 d of static immersion corrosion in 3.5 wt.% NaCl solution. Through electrochemical testing and corrosion-product characterization, it is found that ZCuAl7-7-4-2 has the largest polarization resistance Rp, and the selective corrosion of the surface is mild.
