“…As shown in figure 5(a), the corrosion blocks in the upper part were larger, and as the measurement position changed toward the bottom, the corrosion blocks tended to be finely fragmented, and the relative corrosion degree was also higher. Figure 5(d) and (f) show that a pitting material with a size of approximately 80-100 nm was scattered on both the flat surface and the surface of the block-like structure, and the corrosion products were mainly copper oxides, despite the presence of active elements such as magnesium and aluminum [10] .…”

Phosphor copper is often used to manufacture various shapes of parts, such as nuts, bolts, washers, etc., for connecting and fixing mechanical parts. In the process of coal mining and conveying, it is necessary to relieve environmental pressure by spraying dust reduction. Coal dust combines with fine water droplets to form coal slurry, which adheres and stays on mechanical equipment for a long time, causing structural corrosion, economic losses, and even safety accidents. In order to study the natural corrosion of phosphorus copper in coal slurry water, static immersion test under room temperature environment was used, and the morphology and chemical composition of the sample surface after immersion were analyzed by scanning electron microscopy and X-ray energy dispersive spectroscopy. The results showed that the corrosion products of phosphor copper were agglomerated nanoparticles in coal slurry water, and many carbon elements were left on the surface. In addition, the corrosion resistance, corrosion process and corrosion mechanism of phosphor copper in coal slurry water environment are discussed, which provide a research basis for the corrosion protection of metals in coal slurry water.

“…The corrosion products of copper have the characteristics of high resistivity and strong adsorption, which can effectively protect the internal substrate from further corrosion. According to corrosion tests, the corrosion rate of copper in the soil is about 1/10 to 1/30 that of carbon steel and roughly 1/3 that of galvanized steel, and the corrosion rate of copper is decreasing year by year [ 19 , 20 , 21 ]. The melting point of copper is 1083 °C.…”

A grounding grid plays the role of discharging current and balancing voltage to ensure the safety of the power system. However, soil corrosion can damage the grounding grid, which then can endanger the safe operation of power system. This paper reviewed recent research advances of soil corrosion of grounding grid. The cause, mechanism, types, and influencing factors of soil corrosion of grounding grids were summarized, and the corresponding detection technology and protective measures were also introduced. The paper pointed out that soil corrosion is a serious threat to the grounding grid system. Moreover, the impact mechanism of AC stray current, new corrosion detection technology, and better protective measures still need in-depth research.

Fe-based materials have extensive applications in the building and automobile industries due to their excellent mechanical properties and low cost. However, their biomedical employment is restricted by the corrosion propensity when in contact with bodily fluids. In this study, single-step Plasma Electrolytic Oxidation, PEO, treatment in Ta-rich electrolyte was used, for the first time, to improve the corrosion resistance of low-carbon steel SAE 1020 for possible use as device implants. The effect of the applied voltage on the chemical and phase composition, topography, wettability, roughness, and corrosion properties were addressed. The results indicated that the Fe-based oxide coatings had a rough and hydrophilic surface, increasing the Ta content with the applied potential. The phase composition of the coatings was mainly composed of hematite (Fe2O3), with the Fourier-transform Infrared Spectroscopy, FTIR, spectrums indicating the presence of some absorbed water and organic molecules. The corrosion resistance of the PEO-treated samples was better than the substrate against saline solution (0.9% NaCl) due to the Fe2O3 growth decorated with Ta particles, especially the sample treated at 200 V. The results state that Ta-enriched Fe-based oxide coatings could significantly improve the applicability of low-carbon steel SAE 1020 as a low-cost biomaterial, particularly for medical devices.
