“…Aluminium alloy matrix composites reinforced with ceramic particles exhibit better mechanical properties than unreinforced aluminium alloys [1,2] and have been used as tribological parts in some vehicles for years due to their high ratio of strength/density and better wear resistance [3,4]. Particulate reinforced aluminium alloy composites have shown a significant improvement in tribological properties, including sliding and abrasive wear resistance and seizure resistance [5][6][7][8][9].…”

“…Due to their higher strength to density ratio and better wear performance, these metal matrix composites (MMCs) are used as tribological parts in automative industry [3][4][5]. This is primarily due to the fact that hard dispersoids make the matrix alloy plastically constraint and improve the high temperature strength of the base virgin alloy [6].…”

Wear properties of a nanostructured matrix of Al prepared via mechanical milling and hot extrusion were investigated before and after incorporation of B 4 C nanoparticles. The sample powders were milled for a period of 20 h to produce nanopowders. Mechanical milling was used to prepare nanocomposite samples by addition of 2 and 4 wt% of B 4 C nanoparticles into the Al matrix. A pinon-disk setup was used to evaluate the wear properties of the hot extruded samples under dry condition. The results revealed a lower friction coefficient and a lower wear rate for the nanostructured matrix of Al in contrast to a commercial coarse grained Al matrix. The same pattern was also observed in the nanocomposite samples with respect to the base matrix. Hardness values were used to discuss the observed results. Scanning electron microscopy (SEM) was used to analyze the worn surface and wear debris.

“…AMMCs which are reinforced by ceramic particulates show improvements in mechanical properties as compared to matrix alloy and they are most widely used in tribological applications due to the improved wear resistance, stroke density and high ratio of strength [8]. This is the inducement for increased focus on the use of the direction of particles reinforced Al alloy MMCs for tribological applications [9]. Furthermore, researchers had also studied the immense potential in their properties of Al/SiC/Al 2 O 3 based materials such as better machinability, superior weldability, formability, good castability and better corrosive resistance at high temperature and pressure [10].…”

The Al2O3-SiC reinforced Al7075 Metal Matrix Composite (MMCs) is fabricated through liquid metallurgical technique. Ceramic particulates were amalgamated into aluminium alloy to achieve improved mechanical properties and wear resistance. Al-7075/Al2O3/SiC hybrid MMCs were produced by reinforcing 2%, 3%, 4% and 5% of Al2O3 and 3%, 5% and 7% of SiC particles. Microstructural analysis was carried out to evaluate the uniform dispersal of reinforcing particulates within the base matrix. The output results indicate that the mechanical properties of the hybrid MMCs enhanced by increase the wt. % of ceramic particulates. Tensile fractography results show the internal fracture structure of the tensile test specimens in which the particulates fracture and pullouts were observed. The wear characteristics of developed composites are studied using pin on disc apparatus. The high wear resistance is observed at 5% Al2O3 + 7% SiC reinforced MMCs.
