Ni–Ti Nanocomposite Coatings Electro-Codeposited from Deep Eutectic Solvent Containing Ti Nanoparticles

Abstract

In this work, Ni–Ti composite coatings with well-decentralized Ti were firstly prepared by electro-codeposition with pulse current in deep eutectic solvent (DES) synthesized by choline chloride (ChCl) and ethylene glycol (EG) containing Ti nanoparticles. The electrochemical mechanism of Ni2+ deposition in the presence of Ti nanoparticles in DES were investigated. Moreover, the influences of Ti nanoparticle loading, current density and duty cycle on the levels of Ti nanoparticles loaded into the Ni matrix were systematically explored, in which the contents of Ti nanoparticles could achieve as high as 10.77 wt% when the loading of Ti nanoparticles was only 16 g·l−1 with current density of 5 mA·cm−2 (Frequency = 1000 Hz, Duty cycle = 1/4). Besides, the structure morphology, crystal size and thickness of the composite plating varied with the content of the loaded Ti nanoparticles were studied. Furthermore, the anticorrosion performance of the Ni–Ti plating was significantly improved as the content of doping Ti nanoparticles increased.

Using Deep Eutectic Solvent-Assisted Plating Baths to Electrodeposit Composite Coatings: A Review

“…An interesting approach to the electrodeposition of composite coatings involves the co-deposition of a metallic matrix with metallic particles of a dispersed phase. For instance, the patterns of electrodeposition and the properties of the resulting composites from electrolytes based on DESs containing dissolved nickel (II) salt and nanoparticles of titanium or aluminum have been investigated [73,74]. Specifically, the titanium content in a composite coating depends on the concentration of particles in the electrolyte, current density, and duty cycle when using pulse electrolysis, and can reach approximately 11 wt.% [73].…”

Here, a DES (ethaline) with different loadings of titanium nanoparticles (4, 8, 16, or 32 g L −1 ) was used.…”

Recent Advances in the Synthesis of Inorganic Materials Using Environmentally Friendly Media

“…An interesting example of an “antisolvent approach” is the synthesis of ZnO nanocrystals doped with Cu(II) ions, which involves adding a controlled amount of water to solutions of bulk ZnO in DES [ 67 ]. Few studies have employed DESs other than reline; some noteworthy examples utilize ethylene glycol as the HBD partner of ChCl, the latter being used to obtain nanocrystalline SnO 2 or SnO 2 /graphene nanocomposites [ 68 ], nanoporous Ag films [ 69 ], and Ni-P alloy nanoparticles [ 70 ] to deposit Ni deposits [ 71 ], Ni-Ti nanocomposite coatings [ 72 ], or Ag films [ 73 ]. In an interesting study by Mota-Morales [ 74 ], the dispersant properties of DESs during the formation of nanoparticles and other nanocomposites were exploited for the preparation of a microporous carbon nanotube-polyacrylic acid composite using a ChCl:acrylic acid mixture.…”

Vapor-etching honeycomb-like zinc plating layer for constructing anti-corrosion lubricant-infused surfaces

“…How to improve the corrosion resistance of metal materials is an important research topic in the field of engineering equipment, materials, and advanced manufacturing. Recently, various techniques, including anodic oxidation, cathodic protection, electroplating, and conversion coatings, which can endow the metal substrate with a barrier layer, have been broadly introduced to protect metal from corrosion ( Hou et al, 2020 ; Singh et al, 2023 ; Zehra et al, 2023 ). Among these techniques, Superhydrophobic coating has been considered one of the most straightforward and effective strategies ( Zhang and Xu, 2021 ).…”
