Tribological coatings with low coefficients of friction are in high demand by various industries since they can improve machine efficiency and have an environmental impact. A self-lubricating Ni-P-MoS 2 composite coating has been successfully deposited on a mild steel substrate by electrodeposition. The effects of MoS 2 on the tribological coatings have been investigated. Compared to a pure Ni-P coating, the Ni-P-MoS 2 composite coating exhibited a dramatic reduction in friction coefficient against a bearing steel ball from 0.45 to 0.05. Examination and analysis of the worn surfaces and wear debris, the composite coating showed minimum wear and oxidisation compared to the severe wear and oxidation observed in the pure Ni-P coating. The evolution of MoS 2 particles in sliding wear has been elucidated.

Superhydrophobic surfaces have been intensively investigated for applications requiring self-cleaning and corrosion resistance. The techniques used to fabricate such a coating tend to be costly, time and energy consuming; further surface modification steps are often needed. In this study, a superhydrophobic composite electrodeposit based on a tungsten disulphide nanoparticles dispersed in nickel on a mild steel substrate was successfully developed. At room temperature, the deposit showed a water contact angle of 158.3 deg and sliding angle of 7.7 deg. The effects of operational parameters on surface morphology and superhydrophobicity are discussed. Compared to the substrate, the robust surface of the asprepared coatings exhibited good self-cleaning and corrosion resistance, providing potential for industrial applications.

“…also have described a novel composite luminescent Ni electrodeposit incorporating blue‐emitting phosphor particles for in situ wear detection. For this, a rare earth‐based mixed metal oxide [BaMgAl11O17:Eu 2+ ] was dispersed in an aqueous electrolyte by using cationic surfactant and nonionic surfactants and polyethylene glycol . The effect of particle and additive concentration on the degree of phosphor content was analysed.…”

The diversity of cell geometries and their use for electrochemical processing and energy conversion are concisely reviewed, updating earlier treatments, with an emphasis on an engineering approach to electrode design. Electrode size varies from several cm2 in the laboratory to stacks containing hundreds of m2 at the industrial plant scale, and currents can range from nA at laboratory to many 100 kA in industry. Electrode materials include metals, conductive ceramics and polymers, as well as polymer–metal or ceramic–metal composites. Area, electrocatalytic activity and functionality can be tailored by selecting an appropriate support structure‐coating combination. The core structure of porous supports can be a foam, mesh or particulate bed, whereas the surface can be enhanced using numerous techniques. Inspiration for electrode design can come from multiple sources, including biomimetics and technology transfer. Important aspects of electrodes include manufacture, electrochemical activity, active area, the possibilities of 3D and nanostructured surfaces, decoration and functionalization, in addition to reasonable cost and adequate lifetime. The diversity of electrodes is illustrated by examples from the authors' laboratory in the fields of inorganic and organic synthesis, environmental remediation of wastewaters, surface finishing of materials and energy storage/conversion. A forward look is made to potential future developments in electrochemical technology. © 2018 Society of Chemical Industry
