“…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.

“…From the materials engineering standpoint, the surface of materials has a crucial role since the most hazards usually initiate from the surface defects [1][2][3]. Nanocomposites coatings show brilliant physical, mechanical and chemical properties in different situations, thus they are proposed to be applied on the surface layer of different materials as an effective way to boost their wear and corrosion resistance [4][5][6][7][8][9].…”

One of the important techniques for developing coatings with proper electrochemical and mechanical properties is electrodeposition method. The goal of the current work is to optimise contents of SiC particles in the bath to achieve Ni-B/SiC composite coatings with high corrosion resistance and wear properties. Pulse plating method was used to prepare Ni-B/SiC composite deposits of Watts bath including trimethylamine borane (TMAB) and SiC nanopowder addition. The effects of SiC concentration in the bath, which is the principal factor, on the main properties of the coatings were studied. Field Emission Scanning Electron Microscopy (FE-SEM), Energy-dispersive Spectroscopy (EDS) and X-ray diffraction (XRD) were used to analyse the characterisations of the coatings. In order to evaluate the corrosion behaviour of the coatings, the open circuit potential (OCP), electrochemical impedance (EIS) and potentiodynamic polarisation (Tafel) tests were applied in 3.5% NaCl solution. Moreover, the pin-on-disc procedure was designed to assess the wear behaviour of coatings. Increasing the SiC nanoparticles up to 12 g l −1 in the bath leads to produce a coating including 11 wt-% SiC particles which have a positive effect on the coating microstructure. Corrosion resistance improves by raising 4-12 g l −1 SiC incorporation in the coatings; so that corrosion resistance of the Ni-B/SiC12 g l −1 coating reaches to nearly 62 kΩ. The presence of SiC phase in the coating can result in decrease electrochemical active regions; therefore, this phenomenon can promote corrosion resistance of the composite coatings. Ni-B/SiC 12 g l −1 composite coating illustrates the best wear resistance in comparison with the others after which it shows the lowest weight losses (0.98 mg cm −2 ) and the friction coefficient of 0.57 due to the formation of the packed structures with less porosity and high content of SiC particles in the deposit.

Corrosion of metal products can seriously affect their reliability. The application of coatings is the most widely used method of corrosion protection due to the desire for easy application and low cost. Most of the present corrosion-resistant coatings are solvent coatings. Due to the high content of volatile organic compounds, the use of solvent coatings is restricted. Currently, the corrosion resistance of waterborne coatings is much lower than that of solvent coatings, so research and development of waterborne corrosion-resistant coatings are necessary and valuable. A corrosion-resistant waterborne polyurethane modified epoxy (WPUME) emulsion was prepared and characterized by Fourier transform infrared (FTIR) spectra, transmission electron microscopy, and thermal gravimetric analysis. The particle size, dispersion, and solid content of the emulsion were tested by laser-scattering equipment and a weighing method. Coatings were prepared based on the emulsion, and the properties (i.e., water absorption rate, salt spray resistance, and flexibility) of the coatings were tested by the standard method, respectively. Results show that the synthesis reaction accords well with the molecule design, and the average diameter of the particles in the emulsion is 100 nm approximately. The cured coating, which is coated on tinplate sheets, has good flexibility and can withstand the salt spray test for more than 60 days (i.e., 1,440 h). The emulsion has many potential practical applications in the protection of metal materials.
