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.

“…17 And that this method has been successfully applied to synthesize highly rough inorganic silica films. 18,19 In this context, single-step sol-gel electrodeposition for the fabrication of superhydrophobic surfaces has been investigated. The superhydrophobicity film is achieved as a result of simultaneous generation of organosilanes and inorganic silica component that ensures the formation of highly porous and rough frame work in the organic/ inorganic hybrid sol-gel film.…”

In this study, the superhydrophobic surface with SiO2 nanoparticles and corrosion‐resisting property was prepared on magnesium alloy substrate by a simple one‐step sol–gel electrodeposition. The influence of electrodeposition time on hydrophobicity and morphology of the magnesium alloy surface was discussed. The molecular dynamics simulations were conducted to provide an insight into the interactions between the C16H33Si(OH)3 molecules and the magnesium surface. The results of frontier molecular orbital and Fukui function distributions indicated that the silicon hydroxyl of C16H33Si(OH)3 was the probable reactive site via sharing electrons with metal atoms for the adsorption on the magnesium surface. Quantum chemical calculations indicated that the coordinate bonds could be formed between C16H33Si(OH)3 molecule and unoccupied orbital of metal atom, which led to the active adsorption on the magnesium surface and generate the superhydrophobic surface. The results showed that the superhydrophobic surface could significantly improve the corrosion resistance compared with the pristine magnesium alloy in 3.5 wt.% NaCl solution.

“…Owing to its insufficient mechanical and corrosion protection properties, nickel needs to be alloyed with different metals for industrial components. For this purpose, the electrodeposition of nickel with different elements such as cobalt [6], ferrous [7], tungsten [8], phosphorus [9] and, boron [10], etc. is a hot topic for scientists.…”

In this study, Ni-B/hBN composite coatings were galvanostatically electrodeposited on 304 L grade steel substrates with 50 mA cm −2 of current density from a modified Watt type nickel electrodeposition bath including trimethylamine-borane complex (TMAB), and hBN with the average particle size of 100 nm. The effect of the concentration of hexadecylamine (HDA) as a nonionic surfactant has been investigated. The concentration range was 0-400 ppm. HDA has a significant positive effect on mechanical, tribological and corrosion protection properties of the electrodeposited composite coatings due to its increasing effect on the hBN volume fraction in the coating. According to the results of this study, HDA may be a new nonionic surfactant alternative for metal-matrix composite electrodeposition.
