“…Moreover, this comportment was achieved notably by the cathodic inhibition behaviour of the inhibitor as showed in polarization curves. Many previous reports [51][52][53][54] have linked the inhibition efficiency to the polarization resistance or to the charge transfer resistance, El Faydy et al, and other reports [17,[55][56][57][58] have linked the inhibition effect of an organic compound to the adsorption process which decreases the corrosion rate of the metal. For inorganic compounds, Juttner et al [41] investigated the presence of heavy metal ions (Me Z+ ) as inhibitors of iron corrosion in sodium chloride, sulphate and perchlorate.…”

In this work, we report the thermal, structural and anticorrosive properties of glasses from the xP 2 O 5 -yPbO-zB 2 O 3 system. The prepared materials were characterized using different techniques such as X-ray diffraction, Fourier transform infrared spectroscopy and (FTIR), scanning electron microscopy and differential scanning calorimetry (DSC). DSC analysis showed that the thermal stability increases with the increase of PbO and P 2 O 5 oxides contents. These results were confirmed by density and molar volume measurements. Furthermore, the structural evolution of the studied glasses was followed by FTIR vibrational spectroscopy, and it showed a cross-linking of the glass network upon incorporation of PbO. In addition, the study of the corrosion inhibition of C35 steel by glasses of the xP 2 O 5 -yPbO-zB 2 O 3 system showed that when concentrations of 70 and 700 ppm are used, the corrosion potential rises to around − 437 mV versus SCE, indicating that the glasses of the xP 2 O 5 -yPbO-zB 2 O 3 system change the stability of the metal/solution system to a different stable state. From 70 to 700 ppm, the inhibitor starts to have an effect on the anode current, but it is weaker than the cathode current. The results show that borophosphate glasses are effective corrosion inhibitors for C35 steel in a 1 M HCl environment. At 30 °C, the inhibitory efficiency is around 68% at a concentration of 70 ppm and increases with increasing inhibitor concentrations, reaching 86% at a concentration of 700 ppm.

“…For example, copper circuit boards and copper piping can gradually fail in the corrosive environment. Therefore, it is of great importance to improve the anti‐corrosion ability of CM, and many methods, such as deposition of protective coating, 8,9 adsorption of corrosion inhibitors, 10,11 surface passivation, 12 and so on, have been reported to address this issue. However, these traditional methods would change the inherent structure and properties of the copper surface, affecting the application of CM 13 …”

Copper mesh (CM) is one of the most commonly used engineering materials due to its remarkable mechanical and electromagnetic properties. However, CMs are generally susceptible to chemical corrosion in harsh environments, which greatly limits their long-term usage. In this paper, we come up with a one-step perfluorodecanethiol self-assembly means to manufacture superhydrophobic CM with significantly improved anti-corrosion property. The self-assembly reaction between copper and 1H,1H,2H,2H-perfluorodecanethiol created nanoscale rough structures and lowered the surface energy of the CM surface, which was account for the excellent repellence towards various aqueous solutions. The electrochemical tests demonstrated that, compared with original CM, the i corr value of the self-assembled monolayers (SAMs)functionalized CM decreases about one order of magnitude, whereas the corrosion protection efficiency of the treated CM in NaCl, NaOH, and HCl aqueous solutions were all obviously increased. Therefore, the proposed simple method could be an alternative candidate for the creation of functional CM with anti-corrosion properties that could be used under complex conditions.

“…6 Zinc phosphate (ZP) has replaced chromate in the research of scientists as a less toxic material for metal corrosion protection. [7][8][9][10] The generally accepted corrosion inhibition mechanism for zinc phosphate is pore blocking and the formation of a complex passivation film on the metal surface. The formation of the passivation film blocks the active zone on the metal surface and reduces the corrosion electrochemical reaction rate, thus achieving corrosion inhibition.…”
