Aluminium Al-6061 base composites, reinforced with SiC particles having mesh size of 150 and 600, which is fabricated by stir casting method and their wear resistance and coefficient of friction has been investigated in the present study as a function of applied load and weight fraction of SiC varying from 5, 10, 15, 20, 25, 30, 35 and 40 %. The dry sliding wear properties of composites were investigated by using Pin-on-disk testing machine at sliding velocity of 2 m/s and sliding distance of 2000 m over a various loads of 10, 20 and 30 N. The result shows that the reinforcement of the metal matrix with SiC particulates up to weight percentage of 35 % reduces the wear rate. The result also show that the wear of the test specimens increases with the increasing load and sliding distance. The coefficient of friction slightly decreases with increasing weight percentage of reinforcements. The wear surfaces are examined by optical microscopy which shows that the large grooved regions and cavities with ceramic particles are found on the worn surface of the composite alloy. This indicates an abrasive wear mechanism, which is essentially a result of hard ceramic particles exposed on the worn surfaces. Further, it was found from the experimentation that the wear rate decreases linearly with increasing weight fraction of SiC and average coefficient of friction decreases linearly with increasing applied load, weight fraction of SiC and mesh size of SiC. The best result has been obtained at 35 % weight fraction and 600 mesh size of SiC.

The purpose of this study is to explore the effect of SiC reinforcement along with immiscible element addition in spray formed Al-Si base alloy. The investigation is done for four different compositions, i.e., Al-Si base alloy, Al-Si/SiC, Al-Si-5Sn/SiC and Al-Si-10Sn/SiC composite. The dry sliding wear properties of base alloy and composites were investigated against EN 31 steel at five different normal loads (14.7, 24.5, 34.3, 44.1 and 53.9 N). The tests were carried out in dry sliding conditions with a sliding speed of 1.6 ms -1 over pin-on-disc tribometer. Each composition is tested at four different temperatures 50, 75, 100 and 150°C. To determine the wear mechanism, the worn surfaces of the samples were examined using scanning electron microscope (SEM). The composites emerge to be better wear resistant material than base alloy especially at higher loads. The optimum wear reduction was obtained in Al-Si-10Sn/SiC composite at all the different normal loads and temperatures.

“…3b, from 0.001 to 0.05 m/s, it can be noted that a substantial amount of material is removed. The wear rate indicates a high degree of damage related to the severe wear regime (Akagaki and Kato (36)), but worn surfaces ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 16 appearance and the debris features are typical of a mild wear regime (Zhang and Alpas (22)). For sliding speeds above 0.5 m/s, a clear variation in the morphology is observed although the wear rate remains in the mild wear region.…”

“…Zhang et al (16) carried out wear tests on various aluminium alloys, sliding on air and under non-lubricated conditions. They published an empirical wear mechanism map as a function of the applied load, and the sliding speed showing that the transition from the mild to severe wear regime is determined by wear mechanisms changes, such as mechanically mixing-oxidation, delamination and galling.…”

The investigated slow sliding speeds presented in this work enable the understanding of the wear behaviour on aluminium alloys and could possibly facilitate the completion of the previously proposed wear mechanism map for aluminium at this slow sliding speed range. Dry sliding block-on-ring wear tests were carried out on aluminium alloys, AA5754 (Al-Mg), AA6082 (AlMg-Si) and AA7075 (Al-Zn-Cu), at a very slow sliding speed range (< 0.01 m/s). A bearing steel ring of AISI 52100 was used as counterbody. Tests were performed at varying contact pressures, 20, 100 and 140 MPa, and sliding speeds ranging from 0.001 to 1.5 m/s. The wear tracks and debris collected were examined by scanning electron microscopy (SEM), energydispersive spectroscopy (EDS), and X-ray diffraction (XRD), with the aim of analysing their morphology and composition. At relatively slow sliding speeds (> 0.01 m/s), the specimens exhibited a wear process placed at the mild wear regime, characterized by oxidation and delamination mechanisms of both the aluminium specimen and the steel ring. However, at very slow speed range (< 0.01 m/s), an increase of the wear rate and the friction coefficient isobserved for all the aluminium alloys thus suggesting that an alternative wear mechanism could be taking place.
