“…With the same SiC volume fraction, fine SiC particles have larger total surface area than coarse SiC particles, which results in a more effective restriction of the thermal expansion of the Al matrix. Therefore, the CTE of the composites of fine SiC particles is lower than that of the composites with coarse SiC particles [15]. 5-For all consolidation techniques, the hardness increased by increasing Ni/SiC percent but its value is higher in hot compaction than the other techniques.…”

Al/Ni-SiC composite was prepared via powder metallurgy technique, in which SiC particles were mixed with 10 wt % nickel powder for 24 hrs, then mixed by three percents 5, 10 and 15 wt.% with Al powder in a ball mill for 5 hrs. Three types of sintering techniques were used to prepare the composite. Uniaxial cold compacted samples were sintered in a vacuum furnace at 600 o C for 1 hr. The second group was the vacuum sintered samples which were post-processed by hot isostatic press (HIP) at 600 o C for 1hr under 190 MPa pressure. The third one was the hot pressed samples that were consolidated at 550 o C under the uniaxial pressure of 840 MPa. The results showed that the hot compacted samples have the highest densification values (97-100%), followed by the HIP samples (94-98%), then the vacuum sintered ones (91-97%). The XRD analysis indicated the presence of peaks correspond to Al and Ni, also Al 3 Ni intermetallic and Al 4 Si 2 C 5 phases which indicated that all SiC particles were consumed with Al particles to form Al 4 Si 2 C 5 . Hardness results revealed that hot compacted samples have the highest hardness values. Also the CTE results referred the decreasing of its value by increasing Ni/SiC percent.

A l-SiC composite is made up of Al matrix and SiC particles [1] . Al matrix includes pure Al and Al alloys. SiC particle is a kind of brittle and hard phase and is used to improve the mechanical property of Al matrix.

Nowadays, Polymer composites are frequently used for engineering applications such as aerospace, automotive and marine industries. The present research is on evaluation of wear properties of epoxy resin composite fabricated using alumina (Al2O3) in 5wt% and Silicon Carbide (SiC) in 5-15 wt% in steps of 5 wt% as fillers for testing purpose. The tribological properties such as dry sliding wear characteristics have been evaluated by conducting wear tests using Pin-on-Disc wear testing setup for sliding speed (200/300/400 rpm) and sliding load (20/30/40 N). The wear properties are analyzed using Taguchi’s Design of Experiments and Analysis of Variance (ANOVA) techniques. From the statistical analysis it is found that the 15wt% of SiC is major factor influencing the wear resistance of the composite material. Finally regression analysis has been carried out to build regression model to predict the wear rate of the composite material under different sliding conditions.
