“…The results of Mazurek et al. studies [42] displayed that the microhardness of the hard Ni–B declines by the incorporation of Si 3 N 4 nanoparticles into the matrix. In order to understand well how SiC content affects on the hardness of coatings, knowing Orowan hardening mechanism (which claims the matrix in the composite materials carries the applied force and the reinforcing particles hinder the movement and mobility of dislocations) is not sufficient here [19,41].…”

“…Bakhit et al [41] stated that alloying with cobalt element plays a significant role in reducing the Ni coatings grain size much more than SiC nanoparticles content in the matrix and our experimental results are in good agreement with his work.

“…Sliding led to delaminating some parts of the coating from the substrate. The crushed piece of material could be easily interposed between coating and counterpart leading to considerable fluctuations of the COF curve and consequently, the friction coefficient increases [42]. Sharp microcracks which are propagated approximately perpendicular to the wear direction are a sign of the brittle nature of the deposit and is usually observed in the hard coatings [49].…”

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.

“…Analyzing the literature, it can be easily seen that the problems related to Si 3 N 4 and NI-P are very extensively analyzed. Mazurek et al [ 24 ] showed that Ni-B/Si 3 N 4 composite layers and Ni-B composite layers are characterized by compact structures and a good adhesion to the substrate material. The incorporation of Si 3 N 4 particles into the Ni-B layers increases the degree of surface development of the layers.…”

The article presents the results of mechanical and tribological tests of Ni-P/Si3N4 nanocomposite coatings deposited on the AW-7075 aluminum alloy using the chemical reduction method. The influence of the chemical composition on the Vickers microhardness determined by the DSI method was examined. The nanocomposite layers were made of Si3N4 silicon nitride in a polydisperse powder with a particle size ranging from 20 to 25 nm. The influence of the content of the dispersion layer material on the adhesion to the substrate was analyzed. The abrasive wear was tested and determined in the reciprocating motion using the “ball-on-flat” method. The surface topography was examined by the contact method with the use of a profilometer. Based on the obtained test results, it was found that the Ni-P/Si3N4 layers produced in the bath with the Si3N4 nanoparticle content in the amount of 2 g/dm3 are more resistant to wear and show greater adhesion than the Ni-P/Si3N4 layers deposited in the bath with 5 g/dm3 of the dispersion phase. NiP/Si3N4 layers provide protection against abrasive wear under various loads and environmental conditions.

“…In addition, overly high content of nanoparticles contributes, among others, to reducing hardness and tribological properties. Nanoparticles play a very important role in improving the properties of coatings, but only the proper selection of the dispersion phase, particle size, their content, and possible heat treatment will allow obtaining the optimal coating for given operating conditions [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ].…”

The article presents the results of tribological tests of Ni-P/Si3N4 nanocomposite and Ni-P nickel layers deposited on the AW-7075 aluminum alloy by chemical reduction method, and the AW-7075 alloy without coating. Nanocomposite layers were produced using Si3N4 siliconnitride in the form of a polydisperse powder whose particle sizes ranged from 20 to 25 nm. The influence of the content of the dispersion phase layer material on the abrasive wear, which was determined as the “ball on disc” method, was analyzed. Surface topography was examined by the contact method using a profilometer. The purpose of introducing Si3N4 particles into the Ni-P layer was to increase the wear resistance of AW-7075 aluminum alloy parts with an embedded nanocomposite coating. Based on the obtained test results, it was found that the Ni-P/Si3N4 layers are more resistant to wear than the Ni-P layers and the AW-7075 alloy layers, and are a good barrier against abrasive wear at various loads and environmental conditions.
