“…It is noted that Al-7wt%B samples experience a smaller wear area than the Al-12wt%B samples because of the higher wear resistance caused by the presence of more AlB2 particles. The wear area is basically lower at the speed of 45mm/min and this is consistent with previous research [30]. There is no evident relationship between the coefficient of friction and wear behavior.…”

Mechanical properties and tribological behavior of aluminum matrix composites reinforced with in-situ AlB2 particles AbstractAluminum matrix composites (AMCs) reinforced with in-situ AlB 2 particles have been fabricated using a combination of powder metallurgy, hot rolling and solution treatment. The effects of boron content (7 and 12 wt%), hot rolling and heat treatment parameters on the microstructures and mechanical properties of the composites were investigated by means of scanning electron microscopy (SEM), tensile test and microhardness measurements. The friction coefficient, wear behavior and scratch morphology of the AMCs and pure aluminum were also studied using scratch tests. The hardness and wear properties are higher in a case of composites when compared to unreinforced matrix material.

E-mail address: hanjt@ustb.edu.cn(Jingtao Han) 1. Introduction Aluminum matrix composites(AMCs) reinforced with ceramic particles have been extensively used in the aircraft, aerospace and automotive industries because of their high stiffness, strength to weight ratio, low coefficient of thermal expansion and good wear resistance [1][2][3]. The particulate reinforcements most often added to the pure aluminum or alloys include SiC, SiO2, B4C, TiB2 and Al2O3 [4][5][6][7][8][9]. In previous studies, Khorshid et al. prepared the AMCs reinforced by two sizes of alumina particles by wet attrition milling and hot forward extrusion processes [10]. Haghighi et al. consolidated Al-5 vol.% nano-Al2O3 by equal channel angular pressing and extrusion and compared the physical and mechanical properties [11]. Vajargah et al. fabricated Al/TiB2 nano composites via powder metallurgy route through a primarily...

“…The lowest wear rate was observed with Al10 vol.% AlB 2 composite specimens, while the highest wear rate was observed with the pure (unreinforced) Al alloy. This is in agreement with the wear rate values obtained by Ficici et al [8] and Koksal et al [9]. Similar to particulate reinforced composites, the wear rate decreased with increasing volume fraction of AlB 2 akes.…”

“…This decrease is typical of aligned SiC whisker reinforced alu-minium alloy matrix composites at equal volume fractions [10]. It is assumed that the presence of the reinforcement contributes to a decrease in the friction coecient and consequently a marked decrease in wear rate [8,9]. The average wear rates for Al4 vol.% AlB 2 , Al10 vol.% AlB 2 (latitudinal), Al10 vol.% AlB 2 (longitudinal) cross-sectioned composites, were 10, 45, and 48% lower than that of Al, respectively.…”

Aluminiumboride composites (AlAlB2) having two dierent volume fractions of reinforcing (AlB2), namely 4.0 and 10.0 per cent have been produced through synthesizing boron by reaction of boron oxide (B2O3) with liquid aluminium. Friction and wear characteristic of the composites have been investigated under dry sliding condition and results compared with pure aluminium. The wear rate increases with normal load and sliding speed and is signicantly lower with the composites when compared to that of monolithic material. The coecient of friction increased with increasing volume fraction of AlB2 reinforcement phase. The wear rate, however, decreased with increasing volume fraction of AlB2.

Chopped E-glass fiber-reinforced epoxy composites (10%, 30% and 50%) were fabricated and their mechanical and tribological behaviour was investigated. Three-point bending tests were performed according to the ASTMD790 and tensile tests were performed according to the ASTMD638 standards. Impact tests and hardness measurements of the composites were also carried out. Wear behaviour of composites was studied using pin on disc wear testing device. The design of experiments approach, using Taguchi method, was employed to analyze the results. Signalto-noise ratio and analysis of variance were used to determine the influence of parameters on the wear rate and coefficient of friction.
