17Nanocrystalline Zn-Ni alloys were proposed from a new developed 18 5,5'-dimethylhydantoin (DMH)-based bath as replacement of Zn and Cd coatings due 19 to their excellent corrosion resistance and environmental friendly properties. However, 20 the mechanism of better corrosion performance of Zn-Ni samples compared with Zn 21 and Cd coatings was rare to be investigated. In the present study, the corrosion 22 36 impedance spectra (EIS) confirm the above facts that Zn-Ni alloys have better 37 corrosion resistance than Zn and Cd coatings, which can be used as the best 38 alternative to Zn and Cd coatings. 39

“…A better understanding can lead to an improved deposition system, and an overall superior coating. Work continues to be done in acidic and alkaline conditions with a goal of further improving the materials, longer material lifetimes and a better understanding of the mechanisms involved in various alloy formations [49,50,55,57,59,60,65,[67][68][69][70][71] but little work has been done to examine systems with nanoparticle incorporation.…”

“…During deposition, a thin layer of nickel is initially deposited onto the substrate. As the deposition continues, zinc is intercalated into the nickel, leading to formation of the alloy [57,61,67]. In acidic systems under low current density, a transition from anomalous to normal codeposition has been noted.…”

Nanocomposites - Recent Evolutions

Composite coatings can demonstrate improved property performance as compared to metals and alloy materials. One category of composite coatings is composed of metal or metal alloys with a dispersed phase of nonmetallic nanoparticles. The addition of these nanoparticles has been found to improve corrosion, wear resistance, and hardness. Producing metal composite coatings using electrochemical techniques can be advantageous due to reduced production cost, lower working temperatures, and precise control of experimental parameters. Metal coatings such as zinc have been successfully co-deposited with TiO 2 , SiO 2 , CeO 2 and mica particles and nickel has been co-deposited with a number of materials including TiO 2 , SiC, Al 2 O 3 , PTFE and silicates. Zinc-nickel alloys have long been studied for a number of properties, most notably corrosion resistance and recently their tribological properties. This chapter reviews the literature on electrodeposition of ZnNi nanocomposite coatings. Although there has been much work done on composite coatings, there is much less literature available on composite coatings with zinc-nickel alloys. So in this review, we look at the general trends for nanoparticle incorporation, deposition mechanisms, system stability, microstructures of the coatings and general corrosion trends.
