“…Besides, the matrix grain sizes of TMC-1 and TMC-2 were both around 50 μm. For TMC-3 shown in figure 2(d), in situ TiC and TiB were formed and acted as reinforcements [24]. The average matrix grain size of TMC-3 was the smallest, which was about 30 μm.…”

In this study, three titanium matrix composites (TMCs) reinforced with graphite, graphene, and boron carbide (B4C) were fabricated through powder metallurgical techniques. The morphologies of grains and secondary phases of these TMCs were observed through Optical Micrograph (OM) and Scanning Electron Microscopy (SEM). The results of the mechanical properties of the TMCs showed that B4C was the most effective in increasing the strength and hardness, while the strengthening effect was comparable between graphite and graphene. The plasticity of the graphene reinforced TMC decreased sharply because of the formation of strip-like agglomerations. The small sizes, large volume fraction, and uniform distribution of the secondary phases contributed to the enhancement of strength and hardness in boron carbide reinforced TMC. Although the thermal properties of the TMCs were lower than pure titanium in the temperature range of 25~300℃ , the thermal conductivities of the TMCs were all above 15.6W/m· K.

“…The final product has the characteristics of a small and uniform structure, maintaining the natural state of the raw material with high density. Compared with hot pressing sintering and hot isostatic pressing sintering, the SPS device is simpler to operate, and this technology can be applied not only to the preparation of ceramic materials [19], but also to the preparation of a metal matrix and ceramic composite connecting materials [20].…”

Titanium alloys have been widely used in aerospace and other fields due to their excellent properties such as light weight and high strength. However, the extremely poor tribological properties of titanium alloys limit their applications in certain special working conditions. In order to improve the tribological properties of titanium alloys, the zirconia coatings were prepared on the surface of a TC4 titanium alloy using the discharge plasma sintering method in this article. The influence of sintering parameters on properties such as density, adhesion, hardness, and phase composition, as well as tribological properties (friction coefficient, wear rate) were investigated, and the influence mechanism of the coating structure on its mechanical and frictional properties was analyzed. The results showed that, with the increase in sintering temperature, the density, bonding strength, and hardness of the zirconia coating were significantly improved. The zirconia coating prepared at a sintering temperature of 1500 °C and a sintering time of 20 min had the lowest friction coefficient and wear rate, which are 0.33 and 6.2 × 10−8 cm3·N−1·m−1, respectively. Numerical analysis showed that the increase in temperature and the extension of time contributed to the extension of the diffusion distance between zirconia and titanium, thereby improving the interfacial adhesion. The influence mechanism of different sintering temperatures and sintering times on the wear performance of zirconia coatings was explained through Hertz contact theory.

The applications of AA6082 alloys in the structural and transport are found to be more due its light weight. To improve strength to weight ratio and stress resistance, the carbides/oxides are added and this will leads to improvement in the mechanical properties and high stress sustainability. In this research work, AA6082 Metal Matrix Composite (MMC) is manufactured through the ex-situ casting process with the Silicon Carbide (SiC) reinforcements of 2.5 & 5 wt% and the microstructure evolution, hardness, dry sliding wear behavior and tensile properties of MMCs are investigated. As-cast AA6082 showed the dendritic microstructure with intermetallic eutectics. The presence of SiC particulates in AA6082 resulted in decreased grain size and equixed grains. The hardness of the tested as casted AA6082 samples was found to be 81 HV which has been increased to 93 HV and 107 HV and the tensile strength of AA6082 is increased by 16% and 41% by addition of 2.5 wt% SiC and 5 wt%SiC respectively due to the presence of the SiC particulates. At the same time coefficient of friction of AA6082 is found to be decreased by 11.8% and 20.5% for the testing load of 10N and the corresponding decrease in wear rates were found to be 50.8% and 70.3% respectively. The worn surface showed the continuous groove parallel to sliding direction with short cracks, bidirectional rough grooves with peeled-off SiC, unidirectional smooth scratches along the sliding surfaces for as-cast AA6082, AA6082-2.5 wt SiC and AA6082-5 wt SiC respectively that indicates the significant effects of SiC particulates on wear mechanism.
