“…The dispersed SiC particles disrupt the continuous growth of the coatings, so the surface morphology of the composite coatings becomes more fine, dense and uniform. The fine-grain strengthening effect of the nanoparticles makes the SiC particles play a pinning role in the coatings, restricting the movement of dislocations between the grains, enhancing the mechanical properties of the composite coatings and reducing the deformation during the wear process [45,46]. In the wear process, as the coating wears the SiC particles embedded in the composite coating are gradually exposed on the surface and play the role of load and wear lubricators, so as to reduce the wear on the substrate and enhance the wear resistance of the composite coatings [47,48].…”

To improve the wear resistance of type 45 steel surfaces, Ni–Mn alloy coatings are prepared through electrodeposition under different sodium citrate concentrations based on which SiC particles of varying concentrations are added to prepare Ni–Mn–SiC composite coatings. The coatings are characterized by scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, microhardness testing, surface roughness meter, composite material surface performance testing, and laser scanning confocal microscopy. The results show that adding an appropriate concentration of sodium citrate into the electrolyte can significantly improve the Mn content in the coatings; however, an excessively high concentration increases the residual stress of the coatings and induces cracks on the surface. When the sodium citrate concentration is 40 g/L, the microhardness and wear resistance of the coatings are optimum. The average microhardness of the Ni–Mn alloy coatings is 522.8 HV0.05, and the minimum scratch area of the wear mark is 9526.26 μm2. The addition of SiC particles improves the surface integrity of the composite coatings and further improves the microhardness and wear resistance of the coatings. The composite coating has a maximum average microhardness value of 648.7 HV0.05 for SiC particle concentration of 4 g/L; this value is nearly 25% higher than that of pure Ni–Mn alloy coatings; the minimum scratch area of the wear mark is reduced to 7160.46 μm2.

“…The lattice distortion values were calculated using Equations (6) and (7). Lowangle grain boundaries due to dislocations and lattice distortion are associated with grain refinement in the crystal structure [33]. As the current density increased, negative lattice distortions occurred in the Ni matrix.…”

“…Titanium carbide (TiC) has attracted great attention in many applications as cutting tools, reinforcements in composite materials, and wear resistance materials due to its unique properties such as high melting point, high chemical stability, and outstanding mechanical properties. [1][2][3][4][5][6][7] Since the morphology of the TiC plays a vital role in its performance in the mentioned applications, the morphological controlling of the TiC is very important. [8][9][10] Till now, various methods including chemical vapor deposition (CVD) and powder metallurgy have been proposed for the fabrication of TiC.…”

The effects of hydrofluoric acid (HF) etching time on the morphology of the titanium carbide (TiC) particles with different stoichiometries were investigated. TiC particles with two C/Ti molar ratios of 0.5 and 1.0 were prepared by mechanical alloying.Then, the powders were immersed in the HF solution for different times of 48, 96, and 142 h. Results showed that the morphology of TiC particles greatly changed after HF etching. In general, a roughing phenomenon was observed as a function of the immersion time in the HF solution. The irregular shape of the TiC particles changed to the spherical shapes by increasing the HF etching time. However, the changing tendency of TiC particles with different stoichiometries was different. The shape of prepared powders with a C/Ti molar ratio of 1.0 was polyhedron at the initial stages of HF treatment, while the shape of prepared powders with a C/Ti molar ratio of 0.5 was near-spherical. However, with increasing the immersion time, the shape of both samples changed to a spherical one. The degree of roughing phenomenon of the prepared powders with a C/Ti molar ratio of 0.5 was lower than that of the prepared powders with a C/Ti molar ratio of 1.0.
