Wear corrosion properties of nano-structured SiC–nickel composite coatings obtained by electroplating

Tribo-corrosion of coatings: a review

“…Lekka et al [87] compared the performance of pure nickel and Ni-SiC nanostructured coatings and the results indicate that the codeposition of nickel and SiC nanoparticles leads to uniform deposits possessing 1.6 times higher abrasion resistance and double the corrosion resistance to salt spray attack as well as more stable friction under wear-corrosion conditions. Benea et al [88] studied the wear-corrosion performance of these coatings in a 0.5 M Na 2 SO 4 neutral solution. The nanocomposite coating showed a higher polarization resistance and reduced corrosion current density compared with the pure nickel coating under sliding wear conditions.…”

The rotating cylinder electrode for studies of corrosion engineering and protection of metals—An illustrated review

“…Benea et al studied and compared the corrosion behaviour and friction coefficient of pure nickel and Ni-SiC nanostructured composite coatings as a function of rotating speed in a neutral 0.5 mol dm -3 Na 2 SO 4 media [146]. The composite coating afforded lower corrosion rates, lower friction coefficient and higher polarisation resistance in comparison to a nickel coating.…”

Wear and corrosion behaviour of Al2O3-TiO2 coatings produced by flame thermal projection

“…The properties of the coatings are evaluated by measuring the microhardness, ductility, wear resistance, coefficient of friction and corrosion resistance, which vary according to particle type, size, volume percentage and distribution in the tank [4,5], the thermal projection is a technique that consists of the deposition of coatings with torches that generate the necessary heat to melt the material and accelerate it towards the substrate by means of compressed gas and then the particles collide on the surface forming layers that adhere to irregularities of the surface and allows obtaining high-melting ceramic coatings [6]. Aluminides possess a sufficient concentration of aluminium to form a layer of alumina when exposed to atmospheres of air and oxygen, which makes them have excellent resistance to oxidation and corrosion in aggressive chemical environments [7].…”
