“…China itself is a landlocked country, the per capita share of freshwater accounts for only 1/4 of the total global freshwater resources, and with the rapid development of industrialization and modernization, water resources have been polluted, water quality has declined, and water resources have become more scarce [1]. e eutrophication of water bodies not only harms the growth and reproduction of aquatic animals, but also leads to the destruction of aquatic ecosystems.…”

With the rapid development of the economic system and the continuous development of industry, environmental pollution is becoming more and more important, so wastewater treatment urgently needs to be strengthened. This article uses fly ash-coated iron electrode electrocoagulation method to carry out experimental tests on the treatment of comprehensive wastewater from chemical and pharmaceutical parks. Fly ash is used as a raw material to prepare a shaped adsorbent; in order to analyze whether the adsorbent has many potential applications in actual wastewater treatment and use. The experiment research of iron electrode electrocoagulation was carried out on actual groundwater, aiming to provide data and theoretical support for the utilization of fly ash and the optimization of comprehensive wastewater treatment technology. The article mainly conducts related research on title distribution, firstly the physical and chemical properties of fly ash, and secondly, discusses the related structure of electrocoagulation method, and solves the problem of comprehensive wastewater based on the combination of the two solving issues. Aware of the importance of sewage treatment and the characteristics of related treatment methods such as adsorption, membrane separation technology, and ion exchange, the advantages of these methods are also used for reference in subsequent experiments to achieve the purpose of reliable experimental results. The experimental results show that the effect of sewage treatment with fly ash with different average diameter particles is obvious. Among them, the maximum value of vibration grinding ash before and after application increased from 5.62 to 8.31, and the maximum removal rate is also 8.31; the removal effect is significant. It can be seen that the fly ash-coated iron electrode electrocoagulation method can have a great effect on the treatment of comprehensive wastewater in the chemical and pharmaceutical park.

“…With the development of electroplating technology and nanotechnology, the research on nanocomposite coatings has become the focus of domestic and foreign scholars. The introduction of second-phase particles enhances the performance of these coatings, such as nano-scale SiO 2 [21], SnO 2 [22], Al 2 O 3 [23][24][25][26], TiO 2 [27], SiC [28], PTFE [29], ZrO 2 [30], graphene [31,32], etc. The phase distribution in the nanostructured coating is more uniform than that in micron structure coating since the atoms in the matrix are more firmly bound to the nano reinforcement; the nano-enhancing phase has a more significant enhancement effect than the micron size in the metal system.…”

Ni-P-(sol)Al2O3 nanocomposite coatings were prepared on Q235 carbon steel substrates by pulse-assisted sol-gel method with duty cycles ranging from 20 to 90 %. The production, microstructural characterization, corrosion resistance, friction, and wear properties of Ni-P-(sol)Al2O3 nanocomposite coating were evaluated. The results show that when the duty cycle is 50 %, the surface quality and corrosion resistance of the composite coating are the best, the hardness is 559.6 HV, the corrosion rate is 2.433 mm y −1 , and the friction coefficient is 0.260. In this study, nano sol was used instead of traditional powder doping. The pulse-assisted sol-enhanced composite coating had good wear and corrosion resistance. This technique can effectively avoid the agglomeration of nanoparticles during the deposition of composite coatings while impacting and leveling the coating surface during the pulse interval to improve coating quality. Meanwhile, the highly dispersed sol saves time and energy consumption of mixed solution without dispersant or stabilizer.

“…Electrodeposition has been well-recognized to be an effective technique to fabricate Ni-SiC composite coatings due to various merits such as facile, low cost, large scale, and high productivity, etc. Furthermore, insoluble particles can be incorporated during the growth of Ni layer [7][8]. In principle, the particles with cations adsorption are electrodeposited together with Ni 2+ on the surface of cathode from the electrolyte, facilitating the formation of a composite coating [9].…”

Ni-based composite coatings incorporated with nano/micron SiC particles were fabricated via electrochemical co-deposition in Watts bath, followed by the evaluation of their mechanical and anti-corrosion properties. The micrographic observations suggest that the SiC particles with various sizes can be well incorporated to the Ni substrate. X-ray diffraction (XRD) patterns indicate that SiC particles with smaller sizes could weaken the preferential growth of Ni along (200) facet. In addition, it is found that the incorporated SiC particles with medium micron sizes (8 and 1.5 µm) could significantly enhance the micro-hardness of the Ni composite coatings. Nevertheless, electrochemical measurements demonstrate that micron-sized SiC particles would weaken the corrosion resistance of Ni composite coatings ascribed to the structure defects induced. In contrast, the combined incorporation of nanosized (50 nm) SiC particles with medium micron (1.5 µm) ones is capable of promoting the compactness of the composite coatings, which is beneficial to the long-term corrosion resistance with negligible micro-hardness loss.
