“…When it is realised that the coating matrix may be metallic or a conducting polymer in concert with a dispersed particulate phase which may be ceramic, polymeric or even a second metal and the particles might be spheroidal, tubular plate-like or fibres having dimensions from several nanometres [64] to tens of micrometres [65], the enormous and widening scope of coatings for surface finishing becomes clear [66]. MSA provides a versatile bath for such coatings in electrochemical surface finishing, including a range of nanocomposites.…”

Ever tightening environmental pressure together with the continued need for coatings able to meet challenging service environments have stimulated advances in coating technology. In the case of electrochemical techniques, the classical techniques of electrodeposition and anodising are being upgraded to meet the need for modern surface engineering coatings (including nanostructured films) on metals. A major challenge is to retain conventional processing, including aqueous solutions, simple power supplies and existing electrolyte tanks while using cost effective, 'green' electrolytes. One successful direction has been the emergence of electrolytes based on methanesulfonic acid, MSA which has good electrolytic conductivity and is capable of dissolving many metals as well as acting as a useful medium for dispersion of solids prior to electrophoretic coating. A range of application methods result, including electroplating, anodising and electrophoretic deposition from a stable, aqueous sol. A diverse range of coating materials is emerging, including metals, alloys, porous metal oxide films, conductive polymers and many composites. This review illustrates the usefulness and applications of MSA electrolytes using recent examples from the authors' laboratories and others. Developing coatings, including alternating multilayers of Sn and Cu, nanostructured metals, hierarchical pores, nanotubular metal oxides and graphene composites are briefly considered. This is a review with 94 references.

“…It is interesting to note that electrodeposition of composite coatings containing included nanparticulate ceramic or polymeric particles in metal matrices such as nickel involves enhanced mass transfer of metal ions to the cathode [38, 126,127], representing an opportunity to deploy the RCE for quantitative experimental and modelling studies.…”

“…Electrodeposited Ni-based composites coatings [1] have received a wide attention from the research community in recent years due to the enhanced tribological performance that such coatings may exhibit in terms of coefficient of friction (CoF) and wear resistance [2][3][4][5][6]. Nevertheless, most of the studies available in the literature deal with the performance of Ni-based composite coatings with hard particles, whereas the incorporation of inherently soft and lubricant particles such as hBN or WS 2 into electrodeposited Ni-based coatings has been studied to a much lesser extent [7,8], despite of the enhancement of both CoF and wear resistance that could be expected when lubricant particles [9] are incorporated into Ni coatings.…”

Abstract:The present study is focused on the evaluation of the tribological performance of novel Ni/hBN and Ni/WS 2 composite coatings electrodeposited from an additive-free Watts bath with the assistance of ultrasound. Lubricated and non-lubricated scratch tests were performed on both novel composite coatings and on standard Ni deposits used as a benchmark coating to have an initial idea of the effect of the presence of particles within the Ni matrix. Under lubricated conditions, the performance of the Ni/hBN composite coating was very similar to the benchmark Ni coating, whereas the Ni/WS 2 behaved quite differently, as the latter did not only show a lower coefficient of friction, but also prevented the occurrence of stick-slip motion that was clearly observed in the other coatings. Under non-lubricated conditions, whereas the tribological performance of the Ni/hBN composite coating was again very similar to that of the benchmark Ni coating, the Ni/WS 2 composite coatings again showed a remarkable enhancement, as the incorporation of the WS 2 particles into the Ni coating not only resulted in a lower coefficient of friction, but also in the prevention of coating failure.
