“…AZ31 alloy is known for its superior mechanical properties widely applied in aircraft industries which has aluminium and zinc as major alloying elements of around 3 and 1% respectively. The choice of silica-rich HNT as the primary reinforcement was motivated by its high strength, green nature, corrosion resistance, wear resistance, and non-toxic properties [21,22]. HNT with a structural formula of (H 4 AL 2 O 9 Si 2 .2H 2 O) with an average particle size of 40 nm is utilized.…”

This article examines the effects of combining silica-rich Halloysite Nano Tube (HNT) and Molybdenum di Sulphide (MoS2) as hybrid reinforcements, dispersed at volumes of 2, 4, and 6%, on the surface of AZ31 alloy through the application of the friction stir process (FSP). The prepared composites were analysed to evaluate their microstructure, mechanical properties, wear resistance, and corrosion characteristics. Microstructural observations indicate the occurrence of rapid recrystallization, resulting in reduced grain size and uniform dispersion. The surface composite demonstrates an increasing trend in hardness with the addition of HNT, while hardness decreases with the inclusion of MoS2. The micro tensile test results exhibits that the composite exhibits an increasing trend in strength, while the micrograph of the fractured surface of the micro tensile specimens reveals reduced ductility. The composite displays enhanced wear behaviour with the increasing volume percentages of HNT and MoS2 particles. Solid lubricant nature of the secondary reinforcement and enhanced hardness due to HNT addition and FSP leads to higher wear resistance of the developed hybrid composite. Additionally, the corrosion rate decreases with the addition of HNT, whereas higher concentrations of MoS2 lead to increased corrosion.

“…AA5083 MMCs display several interesting mechanical and physical properties such as considerable strength, low density, significant corrosion resistance, considerable fatigue strength, and improved friction and wear behaviour. Numerous studies have reported the incorporation of several reinforcements to aluminium alloys to improve the tribological characteristics and surface properties such as B 4 C [ 1 , 2 , 3 ], Al 2 O 3 [ 4 , 5 ], SiC [ 6 , 7 , 8 ], TiC [ 9 ], TiO 2 [ 10 ], and ZrO 2 [ 11 ]. Many techniques have been used to fabricate Al-based metal matrix composites such as powder metallurgy, casting technology, and friction stir processing (FSP) [ 12 ].…”

In this study, AA5083–WC composites were developed by ball milling followed by hot consolidation. The microstructures of the developed composites were investigated using XRD, SEM, EDX, and EBSD. The developed composites exhibited a homogeneous dispersion of WC particulates in the AA5083 matrix without any interactions at the matrix/reinforcement interface. The results confirmed the development of a refined equiaxed grain structure of AA5083–WC composites where the EBSD results revealed an average grain size of 4.38 µm and 3.32 µm for AA5083–6%WC (AW-6) and AA5083–12%WC (AW-12) composites, respectively. The results showed that incorporating WC particulates in the AA5083 alloy matrix significantly improved the compressive stress–strain behaviour and considerably enhanced the resistance to wear and friction. The AA5083–12%WC (AW-12) composite displayed the maximum strength and the highest resistance to wear and friction, whereas the as-milled AA5083 alloy (AW-0) exhibited the lowest strength and the least resistance to wear and friction. The AA5083–12%WC (AW-12) composite exhibited the optimum mechanical and tribological behaviour of the developed composites, making it a promising candidate for tribological applications.

“…Due to the properties of high hardness and high wear resistance, ceramic particles such as SiC and TiB2 as a reinforcing phase have been widely used in wear-resistant parts of aluminum-based composites [1]. However, the physical properties of the aluminum matrix and the ceramic particles are quite different, such as the coefficient of thermal expansion, which leads to greater stress when the two materials are combined, and the reinforcement phase is easily peeled off during service, affecting the wear resistance.…”

In the study, Ti fiber (200 μm, 99.8 wt.%) and pure aluminum (99.6 wt.%) were respectively used as the reaction source and matrix to prepare Al-based composites by in-situ synthesis methods. During the stage of preparing the preform, Ti fibers were fixed in the matrix at equal intervals to pre-control the initial position of the product. The preform was heated in an induction heating device finally, at the same time, parameter combinations of different frequencies and currents were applied to promote the in-situ reaction between Al-Ti, thereby the Al matrix composites reinforced by Al3Ti were obtained. The phase composition, microstructure and wear resistance of the composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and wear testers. The results show that when the frequency and current are 5 kHz and 15 A respectively, the Ti fiber is completely reacted, and the product is the isometric Al3Ti with a size of 1 – 2 μm and a particle spacing of about 5 μm, reaching the optimal microstructure under all parameters. Under the condition of a load of 9.8 N, the wear rate of the composites at 5 kHz and 15 A is 2.325 mg/mm2, indicating the best values in this experiment.
