“…Dezincification of the Zn-Ni(ms) coatings could be favoured by the presence of metallurgical defects like pores, grain boundary fraction and/or triple junctions linked to the refinement of the microstructure. [55] To conclude, it seems that the coating synthesised using millisecond pulses presents a lower corrosion protection due to metallurgical features that increase the coating reactivity during the immersion. Besides suitable particle surface functionalisation, [34,35] a reliable alternative for increasing the particle incorporation is the refinement of the microstructure.…”

Pure Zn‐Ni and Zn–Ni–ceria (CeO2) nanocomposite coatings were deposited onto steel substrates using pulse electrodeposition process from an acidic bath combined with preliminary sonication. Influences of different parameters such as pulse parameters, addition of nanoparticles in the electroplating bath, use of sonication to ensure their dispersion, were studied in terms of morphology, composition, and corrosion behaviour in saline solution. Results revealed a strong influence of the electrodeposition parameters on the corrosion behaviour of the Zn‐Ni coatings. Incorporation of ceria nanoparticles is enhanced for the very short duration of the pulse due to the refinement of the microstructure. It was proved that composite coatings present an enhanced corrosion behaviour, while sonification does not afford a further improvement.

In this study, Ni–C films have been fabricated via pulse electrochemical deposition and carbon sol reinforcement methods. The surfacing of prepared films significantly improved due to the uniform distribution of nanoparticles. Additionally, the maximum thickness is attained when the concentration of carbon sol is 15[Formula: see text]ml/L. X-ray diffraction analysis of the Ni–C composite films reveals adding carbon sol effectively refines the grain size of prepared films. The highest film hardness, 420[Formula: see text]HV, is achieved at a carbon sol concentration of 15[Formula: see text]ml/L, corresponding to the best wear and corrosion resistance. Excessive carbon sol can lead to agglomeration of carbon particles, resulting in defects such as cracks and pores within the coating, thereby degrading its performance.

This research comprehensively explores the synthesis of Co–Ni–TiO2 coatings employing a hybrid methodology that integrates sol-enhanced and pulse current electrodeposition techniques. The investigation examined the surface morphology and intrinsic properties of Co–Ni–TiO2 coatings, revealing the significant influence of pulse duty cycle variations on the characteristics of coatings. A detailed analysis indicates that a pulse duty cycle of 0.4 optimized the coating’s performance, offering superior attributes compared to other duty cycle settings. The study elucidates that lower duty cycles foster hydrogen evolution reactions on the cathode surface, culminating in the formation of a porous, needle-like coating structure. Conversely, higher duty cycles are found to mitigate the effects of material replenishment, thereby affecting the coating’s quality and performance. The findings of this investigation not only shed light on the critical relationship between the pulse duty cycle and the properties of Co–Ni–TiO2 coatings but also lay a foundational framework for the further refinement and optimization of these coatings for advanced applications.
