“…An increase in load creates shear stress and causes an increase in temperature at the interface between the counterface material and the sample. Frictional heat causes the plastic flow of the surface and subsurface regions [120–122]. For the worn surfaces of the composites, the degree of plastic deformation was lower than that of unreinforced alloy.…”

The demand for magnesium (Mg) alloys is increasing in many industries, such as automotive and aerospace, thanks to their low density and high specific strength. However, the poor tribological performance of Mg alloys is one of the most important disadvantages that limit their widespread use. Researchers have developed different approaches to improve the wear performance of Mg alloys, such as alloying, coatings, surface modifications and composite production. Wear performance of systems with sliding parts are crucial for a lifetime and energy efficiency. The development of Mg matrix composites can significantly reduce energy loss by reducing damage from friction and wear. For this reason, it is crucial to understand the wear behaviour of recent Mg matrix composites. The effect of different parameters such as load, sliding speed, reinforcement content, reinforcement type and temperature on the wear performance of Mg matrix composites were investigated.

“…Furthermore, homogeneous CNT distribution, wt% of CNTs, its orientation and in-between bonding strength may be held to account for enhancing mechanical properties. Pressure infiltration was used to create TiB 2 and graphene-based AZ91 nanocomposite [14]. When likened to pure alloy, the composite containing just TiB 2 , the ratio of porosity was higher, with higher ratios of graphene, the measured compressive strength was 415 MPa, and for 0.25 vol% graphene added composite, it was 140.6 HB.…”

In the current work, magnesium (AZ91D) matrix composites reinforced with different weight fractions (5, 10, and 15%) of titanium diboride (TiB2) and 1.5 wt.% percent carbon nanotubes (CNTs) are fabricated using stir casting. The improvements in mechanical, wear and corrosion resistance properties are evaluated as per ASTM guidelines. The synergistic strengthening effect of TiB2 and CNT is also studied. It was discovered that the AZ91D/(1.5CNT-10TiB2) composite outperformed other magnesium matrix composites in terms of strength and ductility. Experimental characterization and quantity analysis revealed that the load transfer process of CNT and thermal mismatch, grain refinement are the primary factors leading to the composite's increased tensile strength. Porosity tends to increase as a result of variance in thermal expansion coefficient of particles and matrix material, Orowan strengthening mechanism plays a prominent role towards enhancement of tensile strength. Because of the influence of synergistic strengthening, micro particles TiB2 increased the proportion of load transmission mechanisms and thermal mismatch facilitated the homogenous distribution of CNTs. Wear resistance and corrosion resistance increases with inclusion of CNTs and TiB2 content. Abrasive type wear mechanism is seen from the SEM image and the wear craters are also seen in all the SEM images, adding TiB2 considerably improves the cast composites resistance to corrosion because of grain refinement. Higher addition of TiB2 influences higher pitting corrosion due to poor grain refinement.
