The silicon carbide (SiC) reinforcement with aluminium alloy 7xxx series has been found to be limited value as per the mechanical properties and wear behaviour of previous studies. In order to improve limited mechanical properties of hybrid aluminium metal matrix composites, the SiC and OFHC Cu-Fe29Ni17Co reinforcement has been added with AA7075 alloy. Hence, the AA7075/SiC/Cu-Fe-Ni hybrid composites have been fabricated through a stir casting route under different weight percentages of SiC reinforcement. The mechanical properties such as hardness, compressive strength, tensile strength and wear rate have been investigated. The micro structure of hybrid composites found that the reinforcement particles in matrix alloy have been evenly spread. The silicon carbide and Cu-Fe-Ni alloy in aluminium solid solution has been found as well bonded interfacial reactions. The hardness, tensile strength, yield strength, compressive strength and wear rate were improved by 23.9 %, 48 %, 47 %, 15.3 % and 70 % for hybrid composite by adding 15 wt. %SiC and 15 wt. % Cu-Fe-Ni with AA7075 alloy, compared to matrix alloy.

“…16 By simultaneously enhancing the material's mechanical and abrasion resistance properties, the AZ91D mg alloy's major applications in further vehicle and space satellite components. 17 The most commonly used carbide particles and oxide particles as reinforcement in magnesium and its alloys are SiC, 18 TiC, 19 B 4 C, 20 Al 2 O 3 , 21 Y 2 O 3 , 22 and ZnO 23 to enhance tribological and mechanical behaviours of the resulting composites. In one research, H. Mohammadi et al 24 reported by adding more B 4 C to AZ91, the mechanical properties (compression strength, hardness) and wear characteristics were enhanced.…”

In this study, AZ91 magnesium alloy based metal matrix composites are made-up of bottom pouring stir casting with 0 wt.%, 1.5 wt.% and 3 wt.% boron carbide (B4C) particles reinforcements. The influence of hard reinforcements on mechanical properties such as hardness and tensile strength has been investigated for the casted composites samples. It was found that by adding 1.5 wt. % and 3 wt.% B4C particles, the Rockwell hardness value of 3.2% and 4.6%, Ultimate Tensile Strength (UTS) values of 15.5% and 26.3% of the composites increased respectively. The influence of B4C contents on AZ91D mg alloy wear study was carried out using pin on disc apparatus. Also, the effect of applied load (5N, 10N, and 20N) on wear properties was investigated. The results of the dry sliding wear tests show that AZ91D- B4C magnesium composite has less wear loss than the unreinforced AZ91D magnesium alloy. X-ray diffraction (XRD) analysis were performed for finding the various compounds such as MgO, B4C and Mg17Al12 present in the developed composites. Further, scanning electron microscopy (SEM) analysis were performed on the worn-out pin surfaces to investigate the wear pattern. These findings indicate that the addition of B4C content improved mechanical characteristics and wear resistance, which may also be used in the automotive and aerospace industries.

The tribological behaviour of AZ91D magnesium alloy bottom pouring stir cast with boron carbide (B4C) and graphite (Gr) was examined. The wear and frictional properties of AZ91D magnesium alloy, AZ91D-B4C composite, and AZ91D-B4C-Gr hybrid composite were investigated individually under dry sliding circumstances. To perform the studies, the L9 orthogonal array approach was adopted to investigate the effects of various sliding distances (0.5, 1, and 2 km) and applied load (5, 10 and 20N). When compared to AZ91D magnesium alloy and AZ91D- B4C composite, the wear loss for the AZ91D- B4C-Gr hybrid composite were reduced by 52.2% and 17.76% respectively at maximum load (20N) and sliding distance (2 km). Compared to AZ91D magnesium alloy, the hybrid composite had a higher hardness. SEM analysis of worn surfaces was performed to determine the significant abrasive wear process. The critical factors affecting the wear losses were generated using analysis of variance (ANOVA).
