“…Tungsten disulphide (WS2) is a two-dimensional layered material with particularly good lubrication properties [21], [22]. With the addition of WS2 in nickel-based flow coatings, "cactus-like" structures are often observed, these structures have nodular rough surfaces [23], [24]. This special "cactus-like" nodular structure consists mainly of alloy particles deposited on the granules and WS2 granules partially embedded in the alloy substrate.…”

“…This special "cactus-like" nodular structure consists mainly of alloy particles deposited on the granules and WS2 granules partially embedded in the alloy substrate. In recent years, tungsten disulphide has been used in composite coatings to improve resistance to friction, especially by using it as a solid lubricant [23], [24], [25], [26]. Roy et al studied the Ni-WS2 nanocomposite film produced by pulse electroplating [25].…”

“…This composite film exhibits excellent solid lubrication properties with 1/5 of the coefficient of friction of steel substrates. Liu et al fabricated electroplated Ni-Co/WS2 composite coating [23]. Compared with the Ni-Co alloy coating, the Ni-Co/WS2 composite coating shows that the coefficient of friction is reduced by 3/2 and the corrosion rate is reduced by about half.…”

2D (two-dimensional) materials have been the focus of recent material science studies. These materials are generally lamellated. Due to these physiological properties, they act as solid lubricants as antiwear in parts operating under a certain load. In this study, WS2 particles of 1 micron size were added to the Ni-P bath and Ni-P-WS2 composite coatings were produced at different current densities at the same concentration. The aim of this study is to obtain Ni-P metal matrix composites reinforced with WS2 particles on steel surfaces with high hardness and wear resistance for parts working under intense load in automobiles and aerospace vehicles and for use in anti-wear applications. In the study, WS2 particles were added to the bath at a concentration of 0.1 g/L and 3 coatings were produced at current densities of 13 A/dm 2 , 20 A/dm 2 , 26 A/dm 2 respectively. The effects of different current densities applied during the deposition process on particle distribution, hardness and wear resistance were investigated. During the electroplating process, a suitable stirring speed and a certain temperature were kept constant for the deposition of WS2 particles on the Ni-P matrix. The produced films were characterised by scanning electron microscopy (SEM) and Xray diffraction (XRD) analysis.

“…To provide self-lubrication properties to composites the addition of solid lubricants is required. The most commonly used solid lubricants are graphite [ 48 , 49 ], boron nitride [ 50 , 51 ], molybdenum disulfide [ 52 , 53 ] and tungsten disulfide [ 54 ]. As it was mentioned above, increased thermal conductivity is advised to improve the tribological properties of polymer composites; however, as it was found in [ 29 ], QC fillers do not allow one to increase the thermal conductivity of polymer composites significantly.…”

Antifriction hybrid fluorinated ethylene propylene-based composites filled with quasicrystalline Al73Cu11Cr16 powder, polytetrafluoroethylene, synthetic graphite and carbon black were elaborated and investigated. Composite samples were formed by high-energy ball milling of initial powders mixture with subsequent consolidation by injection molding. Thermal, mechanical, and tribological properties of the obtained composites were studied. It was found that composite containing 5 wt.% of Al73Cu11Cr16 quasicrystals and 2 wt.% of nanosized polytetrafluoroethylene has 50 times better wear resistance and a 1.5 times lower coefficient of dry friction comparing with unfilled fluorinated ethylene propylene. Addition of 15 wt.% of synthetic graphite to the above mentioned composition allows to achieve an increase in thermal conductivity in 2.5 times comparing with unfilled fluorinated ethylene propylene, at that this composite kept excellent tribological properties.

“…Supersonic plasma spraying coating preparation can be conveniently and inexpensively operated, but the bonding strength of the coating is poor [14]. Electroplating can prepare thin coatings for surface modification, but industrial waste water produces environmental pollution [15]. Compared with other preparation methods of coatings, laser cladding exhibits efficiency, low dilution, fine grain sizes, good metallurgical bonding, etc.…”

The microstructure, microhardness and corrosion resistance of laser cladding Al 2 O 3 @Ni composite coating were investigated. The Al 2 O 3 @Ni core-shell metalceramic powders synthesized via electroless plating method were used as laser cladding materials. According to the results of scanning electron microscopy and energy dispersive spectrometer, the microstructure of the Al 2 O 3 @Ni composite coating gradually transitioned from columnar crystal to cellular crystal and equiaxed crystal along the bottom to the surface. Furthermore, the Ni particles and Al 2 O 3 particles separated when laser heating, then formed Ni metallurgical bonding layer and Al 2 O 3 ceramic layer, respectively. The microhardness of Al 2 O 3 @Ni composite coating was up to 917.0 HV, which was about 5.7 times that of 304 stainless steel. In addition, immersion and electrochemical tests revealed that Al 2 O 3 @Ni composite coating exhibited excellent corrosion resistance compared with 304 stainless steel. The corrosion current density of the Al 2 O 3 @Ni composite coating (36.493 lA cm -2 ) was about 67.0% lower than that of 304 stainless steel (110.592 lA cm -2 ). Meanwhile, the corrosion mechanism of Al 2 O 3 @Ni composite coating was revealed. Dense Al 2 O 3 @Ni composite coating can inhibit the penetration of Cland H ? , making the corrosion reaction difficult to occur. Instruction 304 stainless steel is extensively used in chemical plants, food processing and mechanical engineering due to a combination of excellent corrosion resistance, good processing performance and low cost [1, 2]. In most corrosive conditions, 304 stainless steel proves excellent corrosion resistance, because passive film forms on the surface, which can provide important protective properties [3]. However, many
