A REVIEW ON EFFECT ON PROPERTIES OF AL-SIC COMPOSITES FABRICATED BY STIR CASTING METHOD

In the present study aluminium silicon carbide (Al/SiC) composites were prepared by powder metallurgical method. The mechanical and morphological evaluation were studied upon the variation of reinforcements percentages i.e.10, 15 and 20 wt.% of SiC powder were used as the reinforcements in aluminium matrix. The comparison of powder metallurgy method with stir casting method of Al/ (SiC) composites preparation was performed and the particle reinforcements were visualized through Scanning Electron Microscopy (SEM). The results demonstrated increased hardness with increasing wt. % of SiC particles. This was attributed to efficient stress transfer and dislocation strengthening. In addition, the densification behaviour of the composites was also studied and SiC particulates were found to exhibit profound effect on composites density.

This manuscript investigates the Fabrication and Microstructure of Automotive Brake Rotor Made of AlSi-SiC Composites. This work is oriented toward fabrication of automotive brake rotors from Al-9Si and Al-12Si reinforced with 10 and 20% SiC particles using stir-casting method. The brake rotors were subjected to heat treatment. Aging behavior showed that hardness increased with the addition of SiC reinforcements by 104%, comparing to solution treatment condition. Also, the addition of SiC particles accelerates formation of precipitates. Microstructure of brake rotors made of composite revealed uniform distribution of SiC particles, primary phase (⍺-Al) and modified eutectic Si. EDX analysis showed the presence of Al, Mg and O at the interface between matrix and SiC particles.

Sic Composites

Brake blocks is a vital component in the braking system of trains. Generally material brake blocks made of cast iron. But the usage is still less effective than the weight and resistance to wear. Al-SiC composites with the variation of weight fraction of 5, 10 and 15% SiC is expected to address the problem as expected. Stir casting method was chosen for the process of formation of Metal Matrix Composites (MMC), which includes the characterization of microstructure and wear of materials. Wear and tear on the material tested by the method ogoshi at 2.12 kg load and a constant sliding speed 0.244 m/s for 60 seconds. Small value indicates the specific wear resistance of materials against wear is good.
