“…At concentrations greater than or equal to 10 g L −1 , the B content remained constant at 1.5 ± 0.08 at.%. An equivalent behavior for the variation in P during the electrodeposition of the Ni-P-SiC composite has been observed by other authors [9,22,23].…”

“…Likewise, the friction coefficients average values (µ) of the Co-B/SiC coatings, which were obtained simultaneously during the wear test, decreased as the atomic percentage (at.%) of SiC in the coating increased and reached a constant value of ≈0.31 at the highest concentrations of SiC. The obtained friction coefficients values were lower than other reported for systems such as Ni-P/SiC [12,23,30], Ni-B [31], Ni-B-diamond [32], Ni-P/B 4 C [14], and Ni-SiC [33], but were higher than those reported for Ni-P-GDF and hard Cr coatings [19]. The above results imply that the SiC particles occluded in the coating matrix acted as a lubricant since when the content of SiC particles in the Co-B/SiC coatings increased, the lubricating properties of the coatings increased.…”

In this research work, Co-B/SiC composite coatings were synthesized by electrochemical deposition from colloidal suspensions with different content of SiC. The Co-B/SiC films obtained were heat treatment at 350 °C. The composition, morphology, and structure of the Co-B/SiC composite coatings were analyzed using glow discharge spectrometry (GDS), scanning electron microscopy (SEM) coupled with energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD). Hardness and tribological properties were also studied. The results showed that an increase in the SiC concentration in the colloidal suspensions resulted in both an increase in the SiC content and a decrease in the B content in the obtained Co-B/SiC coatings. The Co-B/SiC coatings were adherent, glossy, and soft, and exhibited a homogeneous composition in all thicknesses. Besides, an increase in the SiC particle content of the Co-B/SiC composite coating from 0 to 2.56 at.% SiC reduced the hardness of the film from 680 to 360 HV and decreased the wear volume values from 1180 to 23 μm3 N−1 m−1, respectively (that is, the wear resistance increased). Moreover, when the Co-B/SiC coatings with SiC content ranging from 0 to 2.56 at.% SiC were subjected to a heat treatment process, the obtained coating hardness values were in the range of 1200 to 1500 HV, and the wear volume values were in the range of 382 to 19 μm3 N−1 m−1.

“…Thus, the modification of Ni-P composite coatings is proven to be an efficient method to expand application fields, so introducing particles into these coatings can improve their properties, such as TiO 2 particles, MoS 2 particles, and Al 2 O 3 particles [13][14][15][16]. Generally, the property of the composite coating is closely related to these incorporating particles [17].…”

Protective coatings have received considerable attention for the surface treatment of devices. Herein, in situ grown nanoparticles, TiO2 on Ti3C2Tx sheets (TiO2/Ti3C2Tx), are prepared by a simple hydrothermal oxidation method possessing the layer structure, which is applied to prepare protective coatings. The Ni–P–TiO2/Ti3C2Tx coating is prepared by electroplating technology, revealing more excellent properties than those of the Ni–P coating. Compared with the Ni–P coating, even though the Ni–P–TiO2/Ti3C2Tx coating holds the rough surface, the wettability is changed from hydrophilic to hydrophobic, owing to the gathering existence of TiO2/Ti3C2Tx on the surface and coarse surface texture. In addition, the participation of TiO2/Ti3C2Tx in the Ni–P coating can improve the capacity of corrosion prevention and decrease the corrosion rate. According to the results of hardness and wear tests, microhardness of the Ni–P–TiO2/Ti3C2Tx coating is approximately 1350 kg mm–2 and the coefficient of friction (COF) of Ni–P–TiO2/Ti3C2Tx coatings is about 0.40, which is much lower than that of Ni–P coatings. Thus, the Ni–P–TiO2/Ti3C2Tx coating can be a promising material to protect the surface of equipment.

“…Thus, new innovative coatings, with finely dispersed reinforcement particles are synthesized to provide composite coating with excellent properties. 1,2 Although many deposition procedures of composite coatings are being constantly used, the electrodeposition remains one of the most suitable procedures which represents a trade-off between simplicity and economic concerns. Moreover, it is considered as the major deposition technique industrially used for the codeposition of both metal and particles into composite coatings.…”

Nickel-MoS 2 composite coatings were obtained by electrodeposition from a nickel electrolyte containing suspended MoS 2 particles. The coating composition, morphology, crystalline structure, microhardness, and frictional behavior were studied as a function of MoS 2 concentration. The results obtained in this study revealed that the codeposited lubricant particles strongly influenced the composite nickel coating properties. It was found that increasing codeposited MoS 2 decreases the average grain size of nickel crystallites and leads to the formation of clusters which, in turn, lead to rough coatings with a high and variable thickness. The results of tribological response indicated that the reduction of friction coefficient and the improvement of wear resistance were performed until an optimal value of MoS 2 concentration, which provided the best condition that promoted the tribo-layer stability and maintained the matrix integrity. A comparison of tribological and micromechanical properties between the coating containing the optimal fraction of MoS 2 particles and the coating containing nearly the same fraction of graphite particles has been undertaken. Unlike the case of the addition of graphite particles, the microhardness of composite coating has been enhanced with the incorporation of MoS 2 particles. However, the incorporation of graphite particles in the coating induced more effective lubrication and wear resistance.
