“…Moreover, Ti-based alloys often possess strong oxidation propensity at elevated temperatures which further expedites their degradation due to the formation of porous TiO 2 oxide scale or the embrittlement problem induced by oxygen-rich α-phase [5,6] . In a sense to improve these shortcomings, appreciable investigations have been accomplished toward compositional optimization [7,8] , microstructural modulation [9][10][11] , and surface modification [12][13][14] . Although these strategies have enabled property enhancement of Ti-based alloys, challenges still exist from a processing perspective, since the aforementioned approaches either require the addition of high-cost alloying elements or involve precise control of thermo-mechanical treatment conditions.…”

“…As a result, if researchers can discover a suitable reinforcement to improve the mechanical characteristics of Ti-6Al-4V matrix composites, the Ti-6Al-4V will be able to overcome some shortcomings, such as reduced hardness and Young's modulus [11,12], and find new uses. Because of its high hardness, high thermal stability, high modulus, approximate thermal expansion coefficient, and Poisson's ratio to Ti-6Al-4V matrix, tungsten carbide (WCp) is a preferred choice for reinforcement [13][14][15]. As a result, WCp is likely to be a good reinforcing material for Ti-6Al-4V matrix composites, which should have outstanding mechanical characteristics.…”

“…Titanium dioxide, silicon carbide, titanium carbide, boron carbide, aluminium oxide, titanium nitrate, zirconium carbide, graphite, tungsten carbide, titanium diboride, aluminium nitride, and carbon nanotube are often used in TMCs. The physical, chemical, and mechanical properties of this reinforcement were excellent [11][12][13][14][15][16].…”

The aim of this study is to evaluate the wear and micro hardness of a Ti-6Al-4V matrix reinforced with 10% and 15% tungsten carbide particle (WCp) composite manufactured using the squeeze casting process. Optical microscopy is used to determine the microstructures of the composite. A pin-on-disc wear test equipment and Vickers hardness at atmospheric temperature were used to examine the wear behaviour wear rate, CoF, and micro hardness qualities of primed samples. Loads of 10 N to 80 N, velocities of 4 m/s, and distances of 1000 m to 2000 m are considered for analyzing the wear behaviour of Ti-6Al-4V composites. The wear rate values are 25.683 for 10% WCp, 30.957 for 15% WCp, and 37.683 and 30.957 for 20% WCp. A scanning electron microscope (SEM) is utilized to examine the worn surface of the composites. For 10% WCp, the CoF values are 0.82 and 0.87, and for 15% WC, 0.88 and 0.956. The micro hardness values are 692 VHN for 10% WCp and 835 VHN for 15% WCp. The wear rate, microstructure, SEM images, coefficient of friction, and hardness of TMCs for totaling reinforcing tungsten carbide particle (WCp) possessions were discovered to be improved.

“…In-situ formation of TiC particles have been synthesized by depositing Nickel and graphite on Ti-6Al-4V substrate via laser cladding [16]. Furthermore, the laser cladding of γ-TiAl intermetallic alloys on Titanium alloy has also been achieved [17]. Ti-SiC coating is a prospective candidate for the required improvement of hardness, tribological [18] and oxidation properties of Ti-6Al-4V alloy.…”

The microstructural features and microhardness of ZrB2-reinforced Ti-SiC coatings on Ti-6Al-4V substrate were studied. The deposition of these coatings was achieved via laser cladding technique. A 4.0[Formula: see text]kW fiber-delivered Nd: YAG laser was used to deposit the coatings on the titanium substrate at a laser power of 700[Formula: see text]W and a laser scan speed of 0.8[Formula: see text]m/min. An initial Ti-SiC coating was deposited with no ZrB2 addition followed by deposition of two other coatings with the incorporation of ZrB2 powder at 5 and 10[Formula: see text]wt.%. The coatings were examined using scanning electron microscope (SEM) coupled with energy dispersive spectroscopy. SEM images of Ti-SiC-ZrB2 coatings revealed good metallurgical bond between the coatings and the substrate and also a significant increment in dendritic formation and inter-dendritic eutectics during solidification within the [Formula: see text]-Ti matrix, exhibiting the presence of newly formed phases as the weight percentage of ZrB2 increased. Back-scattered electron images also showed the dissolution effect of SiC particles, as the particle–matrix bond strength is influenced by ZrB2 addition. Furthermore, the microhardness of the Ti-SiC coating was enhanced with increasing ZrB2 weight percentage. X-ray diffraction analysis revealed dominant compounds formed during laser material processing. This study deepens the knowledge of possible microstructural features associated with Ti-SiC-ZrB2 cermet coatings.
