“…Our previous study investigated the Mg/TiB 2 composites and reported that relative densities of the composites decreased with increasing reinforcement content. 6 Hardness results showed an improvement of up to 17% by the addition of 30 wt% TiC particles. The increase in hardness may be attributed to the harder TiC particles, which leads to localized matrix deformation.…”

“…The increase in hardness are coherent with the results of researchers in the literature. 6,17,18 Low hardness values for composite materials can be mainly attributed to the low compaction load, sintering temperature and insufficient sintering time. In another study, Aydin et al 19 have investigated the wear and mechanical behavior of AZ91/TiB 2 composites by powder metallurgy.…”

“…2 So, to improve these low properties of Mg, Mg metal matrix composites (Mg-MMCs) are widely produced with different reinforcements such as SiC, 3 B 4 C, 4 Al 2 O 3 , 5 TiB 2 . 6 Nowadays, TiC is receiving attention as a popular reinforcement material with high hardness and extreme wear resistance. 7 However, the evaluation of the effect of TiC on mechanical, wear and corrosion properties of AZ91 is rather limited.…”

“…1 Hot pressing is one of the methods of powder metallurgy, which enables to acquire higher densification with homogenous microstructure. 6 To the best of our knowledge, there is no study about AZ91/TiC composites by powder metallurgy using hot pressing. So, hot pressing technique was preferred for fabrication of the samples.…”

This study aims to investigate the mechanical, wear and corrosion performances of TiC reinforced AZ91 matrix composites. AZ91 alloy and AZ91/TiC composites with different weight fractions of 10, 20 and 30 (wt%) were fabricated by powder metallurgy incorporating hot pressing. Microstructure characterization shows that partial agglomeration of particles is present especially in AZ91/30 wt% TiC composite. The addition of TiC led to significant improvement in hardness and wear resistance. Observed wear mechanism is abrasive. As compared with AZ91, compressive yield strength and ultimate compressive strength of the composites were also significantly improved. On the other hand, corrosion rate increased with the addition of TiC particles by virtue of presence of the galvanic reactions.

The present study aims to produce graphene nanoplatelet-coated B4C ceramic particle using semi-powder method and to investigate the effect of graphene nanoplatelets on wear and corrosion performance of Al–Si-based metal matrix hybrid composites. For this purpose, first graphene nanoplatelets at different ratios (0.25, 0.5, and 1 vol.%) were coated to the surfaces of B4C particles and then the Al–Si alloy was infiltrated into the reinforcements by gas pressure infiltration method. The characterization of graphene nanoplatelet-coated B4C powders and its composites was carried out by X-ray diffraction, differential scanning calorimetry, scanning electron microscope, and transmission electron microscope analysis. Tribological properties were investigated by reciprocating ball-on-flat method under three different loads (10–20–40 N) in a dry environment. The corrosion resistance was carried out with Tafel polarization method in 3.5% NaCl solution. Characterization results show that graphene coated on the B4C surface was successfully achieved by semi-powder method. After infiltration process, a new phase formation was not observed, but porosity increased with the increase of graphene content. When the boron carbide surface was coated with 0.5vol.% graphene, it was determined that the specific wear resistance increased by 55% and the corrosion resistance decreased by 12%.
