Popis: | Coconut shell is a bio-degradable agro-waste obtained from the coconut processing industry and is found abundantly in India. Due to its low density, suitable chemical composition, ease of availability and cost effectiveness, coconut shell ash (CSA) is a suitable candidate as reinforcement for metal-matrix composites for automotive and aerospace applications. In the present work, coconut shell powder was initially burnt at 700°C in air to form ash. The ash was further treated at 650°C in an inert atmosphere with magnesium and graphite. The composition and morphology of initial and modified CSA was studied using X-ray diffraction (XRD) technique and scanning electron microscopy (SEM) along with energy dispersive spectroscopy (EDS). The density of the particles was also determined. The composite was prepared by compo-casting route by melting AA 1200 aluminium in a stir casting furnace and adding 2, 4 and 8 wt. % (weight percentage) of the modified CSA. The microstructure of the as-cast composite was studied using optical microscopy and SEM. The density of the composite was also determined and related to the amount of filler. Hardness and wear behaviour of the composite were determined using Brinell hardness test and dry sliding pin-on disc wear test at room temperature, respectively |
