“…TiC particles are a widely used reinforcement phase that is employed to produce metal matrix composite [16,17]. It is reported that TiC/Fe composite coating layers have higher wear resistance in dry sliding conditions and can drastically reduce scratching and plastic deformation on the contact surface [18]. Modi et al [19] produced coating layers with Fe-TiC composite and commercial cobalt base (Stellite 6) powders on En31 steel by the tungsten inert gas welding process.…”

Plasma transferred arc (PTA) welding methods were used to produce titanium carbide (TiC) composite coating layers on the surface of 38MnVS6 steel and subsequently deep cryogenic treatment (DCT) was applied to the PTA coating layers. The effects of the TiC powder, different energy inputs (100 and 120A), and DCT on the microstructure and tribological performance were investigated. The microstructure of the composite coatings consisted of cubic TiC, unmelted TiC, and iron matrix. The alloyed and cryogenic treated surfaces exhibited decreases in the coefficient of friction (COF) and wear rate. The average COF of the steel substrate was determined to be 0.373, but for the TiC composite coating layers it varied between 0.236 and 0.33. PTA coating and DCT processes improved the wear resistance 4.5 times compared to the substrate.

“…The reason for this may be explained as follows. First, TiC, acting as a strengthening phase, can effectively reduce the plastic deformation of the matrix during sliding, thus improving the wear resistance of the composites [46]. Second, the grain sizes of the HEA-TiC composites were lower than that of the HEA.…”

Recent studies have suggested that high-entropy alloys (HEAs) possess high fracture toughness, good wear resistance, and excellent high-temperature mechanical properties. In order to further improve their properties, a batch of TiC-reinforced FeCoNiCuAl HEA composites were fabricated by mechanical alloying and spark plasma sintering. X-ray diffractometry analysis of the TiC-reinforced HEA composites, combined with scanning electron microscopy imaging, indicated that TiC particles were uniformly distributed in the face-centered cubic and body-centered cubic phases. The room temperature hardness of the FeCoNiCuAl HEA was increased from 467 to 768 HV with the addition of TiC, owing to precipitation strengthening and fine grain strengthening effects. As the TiC content increased, the friction coefficient of the FeCoNiCuAl HEA first increased and then decreased at room temperature, due to the transition of the wear mechanism from adhesive to abrasive behavior. At higher temperature, the friction coefficient of the FeCoNiCuAl HEA monotonously reduced, corresponding well with the transition from adhesive wear to oxidative wear.wear resistance of HEAs [8,9]. Recently, it was reported that the addition of Cu can reduce the wear rate of CoCrFeNiCux HEAs at both room temperature and elevated temperatures, and wear resistance at elevated temperatures is promoted more significantly than that at room temperature due to their self-lubricating mechanism [10].However, the major challenge for practical applications of the FeCoNiCuAl HEA is its insufficient strength. Recent studies have indicated that the precipitation of reinforcing phases in various materials, such as HEAs and ceramics, can further increase the yield strength of the alloy while maintaining relatively high ductility [11][12][13]. For instance, the precipitation of SiC nanoparticles in FeCoCrNiMn enhanced the compressive yield strength from 1180 to 1480 MPa at room temperature [14]. The precipitation of WC in the FeCoCrNi HEA leads to an improved hardness up to 768HV, which corresponds well with the transition of the wear mechanism [13]. The alloy may also be strengthened by dispersion strengthening, which can significantly improve the strength and hardness of the alloy, and reduce the plasticity and toughness slightly [15]. TiC is considered a good candidate as the strengthening phase due to its high melting point, high hardness, low density, good metal matrix wettability, good chemical stability, and excellent wear resistance [16]. The optimized yield strength of the (FeCrNiCo)Al 0.75 Cu 0.25 HEA reinforced by TiC particles can reach 1637 MPa, which is increased by 90.6% compared to the (FeCrNiCo)Al 0.75 Cu 0.25 HEA [17]. However, the precipitation of ceramic nanoparticles in the metal matrix tends to be unevenly distributed, which is probably originated from the instability of the interfaces between the ceramic particles and the metal matrix [18][19][20]. In order to make the second phase uniformly distributed in the matrix, in situ methods are widely used to fa...

“…[10][11][12][13][14][15][16][17] Among those materials, TiC and TiN exhibit an inherent spectral selectivity which can be used for delivering high-performance SSAs. [17][18][19] However, they tend to oxidize in the targeted operating temperature range. [20][21][22] As most single-phase materials do not naturally have the required behavior (in terms of both thermal stability and spectral selectivity) as SSAs, how can we further enhance the working temperature of SSAs beyond 600 1C?…”
