Silicon Carbide Particulate

The low-cost production and performance of 6061-aluminium alloy matrices reinforced with coated silicon carbide particulate has been studied. The micro-wave vacuum sintering was adopted to prepare the composite in order that the loss ignition is very small. The effect of copper coated silicon carbide has proved beneficial to interfacial bonding and improved the mechanical properties. Differences in the fracture characteristics of specimens containing coated and non-coated particles were observed. The particulates size has much influence on mechanical properties.

The addition of silicon carbide (SiC) as a reinforce in a composite can improve mechanical properties. In this study aluminium ADC 12 (Al-Si-Aluminium Alloy) is treated with an addition of SiC varied from (1; 1.5; 2; 2.5 to 3) vf% and mixed with 0.18 wt% Sr to change the morphology of the silicone eutectic phase and 0.15 wt% titanium boron (TiB) was added as a grain refiner as well as the addition of 5 wt% magnesium (Mg) to increase the wettability. All materials were fabricated by stir cast method. This research is conducted to obtain the candidate material for application in train's brake shoe and bearing. This kind of usage requires high mechanical properties such as wear resistance, thermal resistance, good elastic modulus and lightweight. The composites were characterised by both mechanical properties and microstructure. The result shows that there is an increase in the mechanical properties of aluminium ADC 12 /SiC composite compared to unreinforced with the value of 144 MPa of strength, 53 HRB of hardness, and 0.0049 mm3 m–1 of wear rate. As a result, the higher addition of the SiC results in the better mechanical properties for the composite.

Matrix Composites

Metal matrix composites are the resultant of combination of two or more elements or compounds, possessing enhanced characteristics than the individual constituents present in them. This paper deals with the fabrication of Al 2014-SiC composite and investigation of its Microstructure and Mechanical properties. 2014 Aluminium alloy is characterized by good hardness. It is selected as the base metal. The Silicon Carbide is characterized by good strength and low density (3.21 g/cm3). It is chosen as the reinforcement. Silicon Carbide is coated with Nickel by electroless method to increase its wettability and binding properties. The fabrication of metal matrix composites is done by stir casting in a furnace, by introducing the required quantities of reinforcement into molten Aluminium alloy. The reinforcement and alloy is mixed by means of stirring, with the help of a stirrer. The base alloy and the composites are then tested for mechanical properties such as tensile strength, flexural strength, impact strength and hardness. The fabricated samples have higher tensile strength and impact strength than the alloy. Microstructure of the samples, are analyzed using optical microscope.
