Dry sliding wear behaviour of in situ Al–TiB2 composites

Production and characterization of titanium carbide particulate reinforced AA6061 aluminum alloy composites using stir casting

“…Silicon carbide (SiC) and alumina (Al 2 O 3 ) are extensively used as particulate reinforcements to prepare AMCs over three decades since the advent of AMCs. The development of various production methods made it possible to incorporate several potential ceramic particles such as fly ash [4], SiO 2 [5], TiO 2 [6], AlN [7], Si 3 N 4 [8], TiC [9], B 4 C [10], TiB 2 [11] and ZrB 2 [12] to prepare AMCs.…”

Analysis of Dry Sliding Behavior of Al2O3/B4C/Gr Aluminum Alloy Metal Matrix Hybrid Composite Using Taguchi Methodology

“…Newer processing routes are emerging in the field of composite processing which includes microwave processing [12], diffusion bonding, stir casting, infiltration process, In-situ reactive process and spray deposition and consolidation [13], however stir casting processes is the oldest and cost effective method for producing MMC of metals having lower melting temperature such as aluminium and magnesium [14][15]. The experimental work of Niranjan and Lakshminarayanan [16] was based on the investigations of dry sliding behavior of the aluminium based composites reinforced with titanium boride reinforcements. The authors concluded that wear properties were significantly improved due to the uniform dispersion of reinforcement and strong particle/matrix bonding which were characterized by the relevant techniques such as SEM and XRD.…”

Dry sliding friction and wear behavior of (TiB2+h-BN)/2024Al composites

“…Fig. 8(d) shows the EDXS result of the surface of compacted layer, it can be seen that Fe, O and Al are the main elements, indicating transfer of material and severe oxidation reaction occur during the wear process [8,28,29]. In Fig.…”

“…TiB 2 has emerged as an outstanding reinforcement because of its high hardness, high stiffness, excellent wear resistance and low reactivity with aluminum matrix [8,9]. M. Zhao et al [10] investigated friction and wear properties of TiB 2 /Al and SiC/Al composites fabricated by pressure infiltration technique under certain experimental conditions (P = 0.49 N and V = 0.8 m/s) sliding against GCr15 counterpart on a pin-on-disk wear tester.…”

“…They found that the coefficient of friction was as low as 0.16 because of the existence of H 3 BO 3 during the dry sliding test, however, due to the controlling wear mechanism of adhesive wear, the friction coefficient and wear rate of SiC/Al composite are higher than those of TiB 2 /Al composite. K. Niranjan et al [8] found that low volume fraction in situ TiB 2 /Al composite showed lower friction coefficient because of the homogeneous distribution of TiB 2 in the matrix. Meanwhile, in TiB 2 / TiAl composites, with the increase of TiB 2 volume fraction, the wear rate decreased and the friction coefficient was nearly constant [11].…”
