In this research, Ni-W/SiC composite coatings were electrodeposited from a plating bath containing suspension of SiC particles. The influences of SiC particle concentration in the plating bath on the composition of composite coatings were investigated. The surface morphology and composition of the composite coatings were characterised by scanning electron microscopy, energy dispersive X-ray measurements and X-ray diffraction analysis. The corrosion characteristics of Ni-W/SiC composite coatings were investigated by mass loss and electrochemical measurements, including open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarisation in a 3?5 wt-%NaCl solution. The results showed that the addition of SiC particle to the deposition bath of Ni-W significantly increased the corrosion resistance. The significant improvement in corrosion resistance observed for Ni-W/SiC composite coatings (17100 V cm 2 ) compared to Ni-W (5619 V cm 2 ) could have resulted from the microstructural differences. ExperimentalA platinum sheet (geometric area of ,20 cm 2 ) was used as an insoluble anode and copper sheets (geometric area

“…[11] Ni-W-B coatings have different engineering applications, especially as heat microexchangers, because of some great features like mechanical durability, great hardness, and good corrosion resistance. [11] Moreover, Ni-W-B catalyst (in comparison with other Ni-based catalysts) displays better selectivity and activity in hydrogen production and also appropriate thermal stability. [12] By adding boron sources to the Ni-W electrolyte, Ni-W-B coatings could be deposited.…”

“…Ni–W–B deposits have been introduced as a proper and practical replacement for chromium coatings. [ 11 ] Ni–W–B coatings have different engineering applications, especially as heat microexchangers, because of some great features like mechanical durability, great hardness, and good corrosion resistance.

“…[ 12 ] By adding boron sources to the Ni–W electrolyte, Ni–W–B coatings could be deposited. These sources include sodium borate, [ 11,13–15 ] amine boranes (like dimethylamine borane and trimethylamine borane [TMAB]), [ 12,16 ] a borohydride, [ 17,18 ] boron phosphate, [ 19 ] and boron particles. [ 20 ] By optimizing the operational conditions in plating of Ni–W–B coatings, high hardness (about 850 HV) and good corrosion resistance (7000 Ω·cm 2 ) could be attained.…”

Herein, the effect of WC content (ranging from 0 to 12 g L−1 in the bath) is studied on the corrosion and wear properties of the Ni–W–B/WC pulse‐plated composite coatings. Results display that at the first step, increasing WC concentrations in the bath (up to 4 g L−1) increases WC content in the coating. However, further addition of WC particles decreases WC content in the coating because of the agglomeration of nanoparticles. Furthermore, the corrosion and wear resistance of the deposits improve considerably with raising the WC amount in the deposits. In other words, the coating electroplated at 4 g L−1 of nanoparticles in the bath displays the best electrochemical and wear behaviors. The uniform distribution of reinforced particles in the deposit is the main reason for achieving superior properties. A maximum corrosion resistance of about 65.8 kΩ cm2 is attained in the coating with 4 g L−1 WC in the bath. In addition, this coating displayed minimum values of wear weight loss (0.288 mg cm−2) and the friction coefficient (0.348). Higher WC contents in the bath negatively affect the properties of the coatings because of the existence of agglomerated particles and decreasing nanoparticle amounts in the coatings.

“…Amorphous, crystalline and nanocrystalline forms of Co-W and Ni-W electrodeposits have been reported in the literature. [10][11][12] The development of Co-W and Ni-W alloys with amorphous or nanocrystalline structures is expected to be of particular future interest since materials with such microstructures often possess better corrosion resistance and tribological properties when compared to their crystalline counterparts.…”

Corrosion behaviour of Co-W coatings deposited on copper substrates was studied in 3?5 wt-% NaCl aqueous solution using polarisation technique. The physicochemical characterisation of the alloy coatings was studied by scanning electron microscopy and energy dispersive X-ray analysis techniques. The study revealed the extent of shift in corrosion potential towards the noble direction and the decrease in corrosion current density for Co-W coatings. Among the various Co-W coatings studied here, the Co 78?5 W 21?5 coating presented the best corrosion behaviour and superior corrosion potential compared to pure cobalt coating. In addition, their catalytic activity towards methanol electro-oxidation in alkaline medium was assessed by cyclic voltammetry technique. In cyclic voltammetry studies, Co-21?5 wt-%W electrode shows a significantly higher response for methanol oxidation than pure cobalt electrode.
