Wear behavior of alkaline pulsed electrodeposited nickel composite coatings reinforced by ZnO nanoparticles

Enhancement of Corrosion and Wear Resistance of Ni–P Coatings Stems from the Synergistic Effects of Cr3C2 and Heat Treatment

“…The behavior observed during friction of heat-treated composite coatings at 400 °C mainly stems from the fact that the densification of the heat-treated composite coatings increases the contact area between the abrasive balls and the coating surface, resulting in a smoother surface. This increased contact area also increases the cohesion between the Cr 3 C 2 ceramic particles and the substrate, reducing the potential for friction-induced fracture or segregation, thus reducing the COF …”

Gradient doping of Cu(I) and Cu(II) in ZnO nanorod photoanode by electrochemical deposition for enhanced photocurrent generation

“…The latter is interesting because it is inexpensive, achievable at low temperatures, allows modulating the morphology of ZnO (thin layers or high-quality nanostructures) by adjusting the deposition parameters (potential, current density, bath temperature and precursor concentration [25]). In addition, several literature studies have confirmed that doping ZnO nanocrystals with an adequate amount of Mg, Ni, Al , Fe and Cu [26][27][28][29][30][31], modifies its electrical, magnetical and optical properties. In particular, Cu is considered an interesting dopant due to its low cost and its many chemical and physical characteristic similar to those of Zn due to the similarity of its electronic structure, leading to the replacement of Zn by Cu in the low-energy ZnO lattice [32].…”

Probing into the properties of B4C reinforced nickel phosphorus-based nanocomposite coating

“…Similarly, elastic modulus (Ec) also increased from 8.68 GPa to a maximum value of 14.44 GPa along with the hardness, which increased from 5.0 GPa to 7.6 GPa for the incorporation of 1.0 g/L of BCNPs. The increase in elastic modulus and hardness can be attributed to the combination of dispersion hardening, grain refinement and formation of composite structure [30,53,54]. It can be ascribed as the incorporated hard BCNPs restrict the slip dislocation resulting in improved fracture mechanics.…”
