“…This is since during the initial run-in phase of friction, the more enormous load is carried on the ZrB 2 reinforced particles, the actual contact area between the composite material and the friction sub is small, the resistance during friction is more minor, and the friction coefficient is more minor. As the friction test proceeds, the contact area increases, the friction resistance gradually increases, and the value of the friction coefficient climbs rapidly [2,15,16]. At lower temperatures (room temperature, 50 °C, 100 °C, 150 °C), the overall friction coefficient of ZrB 2 /A356 composites was relatively flat, with less fluctuation as the test proceeded, no sharp peaks, and relatively stable friction properties.…”

The ZrB2/A356 composite material was prepared by using chemical in-situ reaction technology. The high-temperature friction and wear test of ZrB2 /A356 aluminum matrix composites was carried out. The friction and wear test temperatures were normal temperature, 50°C, 100°C, 150°C, 200°C, 250°C, and 300°C. XRD, TEM, SEM and XPS were used to analyze the microstructure, phase and the formation of surface compounds of the composites under different wear temperatures. The results show that the composite phase is composed of ZrB2 and ɑ-Al, and there is a small amount of AlSi eutectic phase；ZrB2 particles are small, hexagonal nearly elliptical, flocculent and well bonded to the matrix; The wear properties of composites are susceptible to temperature changes, and the wear rate is small below 200 °C. The main wear mechanisms are oxidation wear and abrasive wear. When the temperature reaches above 250 °C, the wear rate begins to rise sharply, and a large number of plastic deformation traces and wear debris appear on the surface of the wear spot, and the surface of the wear debris adheres to the protrusions. The primary wear mechanism is adhesive wear. In the stages of oxidative wear, and abrasive wear, although the friction coefficient changes, it is stable. But in the adhesive wear stage, the friction coefficient becomes very unstable and a sharp peak appears. XPS analysis showed that the compounds formed in the wear scar were mainly Al2O3.

“…Steel machining chips in powdered form, having a particle size of 40 to 60 microns, were used as reinforcement in AA 6061 matrix by Md Sumair et al [ 57 ]. First, 5% and 10% weight fractions of chips were reinforced through the stir-casting method.…”

In recent years, many alloys as well as composites of aluminium were developed for enhanced material performance. AA 6061 is an aluminium alloy that has extensive applications due to its superior material characteristics. It is a popular choice of matrix for aluminium matrix composite (AMC) fabrication. This study provides a review on AA 6061 aluminium alloy matrix composites produced through the stir-casting process. It focusses on conventional stir-casting fabrication, process parameters, various reinforcements used, and the mechanical properties of the AA 6061 composites. Several research studies indicated that the stir-casting method is widely used and suitable for fabricating AA 6061 composites with reinforcements such as SiC, B4C, Al2O3, TiC, as well as other inorganic, organic, hybrid, and nanomaterials. The majority of the studies showed that an increase in the reinforcement content enhanced the mechanical and tribological properties of the composites. Furthermore, hybrid composites showed better material properties than single reinforcement composites. The usage of industrial and agricultural residues in hybrid composites is also reported. Future studies could focus on the fabrication of AA 6061 nanocomposites through stir casting and their material characterisation, since they have great potential as advanced materials.

Aluminium is one of the widely used metals in industrial sector owing to its specific features and its commercial production started in late 19th century. In its natural form it is combined with oxygen and other elements and is the third most abundant metal in the earth’s crust. It can be machined easily and has a Face Centred Cubic (FCC) structure. Aluminium alloys are an attractive alternative to ferrous materials for tribological applications due to their low density and high thermal conductivity. The microstructure of aluminium alloys can be modified and mechanical properties can be improved by alloying, cold working and heat treatment. The present work mainly focuses on the study of the effect of variation in composition on the wear characteristics and compressive strength of aluminium alloy Al6463 by varying the compositions of the two major alloying elements, Magnesium (Mg) and Silicon (Si) in the alloy. Four specimens of the aluminium alloy Al6463 are prepared each for Magnesium composition varying b/w (0.5 to 0.875%) and Silicon composition varying b/w (0.2 to 0.575%). Wear and compression tests were carried out as per ASTM standard. The results of the wear test indicate that the least wear rate was obtained for specimens of 0.750% Mg and 0.575% Si composition of the alloy Al6463 at a higher load of 1.5 kg. Also, the compression test results indicate that the specimens with 0.750% Mg and 0.575% Si compositions of the alloy Al6463 exhibit better compressive strength.
