Summary: The hydrophobicity and corrosion resistance of composite coatings can be effectively improved by changing the electrodeposition method and adding inorganic nanoparticles. The incorporation of WS2 nanoparticles significantly increased the surface roughness of Ni-Co coatings. Direct current electrodeposition mode achieved the best hydrophobicity and corrosion resistance, while pulsed current electrodeposition method was more conducive to improving the electrodeposition performance of the nanocomposite coatings.

Summary: The electrodeposition of beta-PbO2 into vertically arranged black titanium oxide nanoarrays (BTN) to prepare an electrode (Ti/BTN/beta-PbO2) for advanced oxidation treatment was investigated. The study found that Ti/BTN/beta-PbO2(5 s) showed the greatest photoelectrocatalysis, while Ti/BTN/beta-PbO2(30 min) demonstrated the best ability to degrade pollutants due to the presence of colloidal PbO(OH)2 generating electroreactive species. Additionally, the activity and stability of Ti/BTN/beta-PbO2 were attributed to the vertical electrons transfer channel provided by BTN and the interlocked structures formed between BTN and beta-PbO2.

Summary: Ni-P/TiC nanocomposite coatings were developed on HSLA substrates through pulse electrodeposition, with different concentrations of TiC nanoparticles. The coatings exhibited improved structural, compositional, mechanical, wear, and electrochemical properties, with Ni-P/0.75TiC composition showing the highest mechanical response and lowest wear rate. The corrosion resistance of Ni-P coatings was substantially increased by incorporating TCNPs, with Ni-P/0.75TiC coatings demonstrating the highest corrosion protection efficiency of 94% in saline water due to the compact structure containing inactive TCNPs in the Ni-P matrix.

Summary: The present study examines the effects of duty cycle in pulse reverse electrodeposited copper foil during electrodeposition and annealing. Results show that increasing duty cycles lead to a decrease in grain size and an increase in twin boundaries and crystallite size. However, after annealing, the average grain size increases and the fraction of twin boundaries decreases with an increasing duty cycle. The differences in anodic period and stored energy play important roles in regulating twin probability and grain size during the deposition and annealing processes.

Summary: This study explores the potential use of duty cycle variation to improve the mechanical and surface roughness properties of Ni-Al2O3 nanocoatings through pulse electrodeposition. The nanocomposite coatings with varying duty cycles ranging from 20% to 100% were analyzed using bearing area curves and power spectral densities to assess their areal and surface roughness properties. The results demonstrate that a decrease in duty cycle leads to an enhancement in both aerial and surface roughness properties, attributed to variations in grain size caused by different time intervals during pulse coatings. The increase in grain size with changing duty cycle was confirmed with scanning electron microscopy. Furthermore, an increase in grain size with an increase in duty cycle resulted in a decrease in nanohardness. This research provides a novel method for obtaining Ni-Al2O3 nanocomposite coatings with improved surface roughness and hardness properties for wider industrial applications.

Summary: Nickel and nickel-iron modified glass carbon electrodes were prepared by electrodeposition in 20 mmol/L NiSO4 and 5 mmol/L FeSO4 + 20 mmol/L NiSO4 solution. The electrocatalytic oxidation of urea at two modified electrodes under alkaline conditions were investigated. In 1 mol/L NaOH solution, the nickel modified electrode showed better results than nickel-iron modified electrode for the electrocatalytic oxidation of urea. The effects of different urea concentrations, different NaOH concentrations, and different scan rates on the electrocatalytic properties of the two modified electrodes were investigated.
