“…Thus, literature studies have shown that Ni–P coatings, regardless of the P content, are characterized by a better corrosion resistance (a lower corrosion rate) compared to steels. The corrosion tests presented in this paper are in accordance with the results obtained in [ 48 , 49 , 50 , 51 , 52 ] and confirm the better corrosion resistance of the Ni–P coating comparing to the Nimax substrate steel, regardless of the immersion time.…”

The common occurrence of the phenomenon of cavitation in many industries and the multitude of factors affecting the resistance to cavitation erosion of used materials contribute to the search for methods and appropriate parameters of coating application that are able to minimize the effects of erosion. To determine the validity of the developed application parameters and the method used, cavitation studies and microscopic observations of the development of erosion during the cavitation test were carried out. There was a clear lack of incubation time and a linear increase in losses after 60 min of the test. Moreover, the damage observed during the test overlapped, widening the area of erosion and thus leading to damage to the integrity of the coating.

“…By comparing the values in Figure 8(c), it was known that the R p of the NiCrAlMoCeO 2 coatings in the 3.5 wt% NaCl solution was ∼70 times than that in the 1 M HCl solution, implying its better anti-corrosion prevention for the substrate in neutral solution. Due to the corrosion product films being less stable and having relatively higher solubility in acidic solutions, 44,45 which eventually showed better passivation stability and more effective anti-corrosion prevention in the 3.5 wt% NaCl solution.…”

Q235 steel is a low-cost material widely applied in modern industrial constructions. However, electrochemical degradation is the main drawback for its applications in chloride-enriched environments. To address this problem, NiCrAlMo and NiCrAlMo + 2 wt% nano-CeO2 composite coatings were laser-cladded on Q235 steel substrates. Characterization methods were used to investigate the microstructures, corrosion behaviors, and electrochemical mechanisms of the obtained coatings. The results showed that adding nano-CeO2 is conductive for removing residual gas pores and for refinement of grains, effectively improving the passive and electrochemical properties of the NiCrAlMo coating in both chloride-enriched solutions. Furthermore, the NiCrAlMoCeO2 composite coating exhibits a significantly reduced icorr of 0.4919 µA cm2 and an increased resistance ( Rp) of 175,310 Ω cm2 in a neutral solution, demonstrating the good anti-corrosion properties for its application in marine engineering structures.

“…The binding energies of 856.1 and 873.6 eV were attributed to the 2p 3/2 and 2p 1/2 spin–orbital components of Ni 2+ , respectively. Additionally, the corresponding satellite peaks were near 873.4 and 861.9 eV, respectively, which further confirmed the chemical state of the Ni 2+ . − As shown in Figure c, there was a strong peak at 531.7 eV in the O 1s spectrum, which proved that the O element existed almost entirely in the form of O 2– . , Figure S2 shows HRTEM image of Cu 2 O/NiO heterostructure ordered nanoarrays. The spacing of the lattice is measured to be 0.26 and 0.21 nm, corresponding to the (111) plane of Cu 2 O and (200) plane of NiO.…”

Magnetism is a promising external intervention for gas sensitivity based on a heterogeneous interfacial structure caused by the regulation of the heterogeneous interface conductivity and the surface oxygen adsorption. In this study, Cu 2 O/NiO heterostructure-ordered nanoarrays were prepared with a two-dimensional (2D) electrodeposition in situ assembly method for H 2 S gas detection at room temperature under the action of a magnetic field. The nanoarrays were multibarrier structures with a strictly periodic structure that was greater than hundreds of microns in size. The experimental data confirmed that the response of 50 ppm of H 2 S based on the nanoarrays was improved by nearly 61% with a relatively weak magnetic field. Particularly at a low concentration (≤20 ppm), the effect of the magnetic field enhancement on the sensitivity was more obvious. We attributed the enhancement of the gas sensitivity with the magnetic field to the regulation of the Cu 2 O− NiO interface conductance and the surface oxygen adsorption. This study demonstrated that a magnetic field could significantly enhance the gas sensitivity based on heterostructures. Results of this study provide an important reference for the application of magnetism in gas detection and the design of new gas-sensitive materials.
