Abstract

A new class of metal matrix composites known as aluminum hybrid composites has the potential to meet the demands of modern advanced engineering applications. However, their performance was based on the combination and the nature of the reinforcements. The bio-shell waste of snails left over from restaurants and eateries poses a serious environmental threat with little or no economic value. So in this research, an effective utilization of low-cost materials such as aluminum alloy wheel scrap and silicon carbide (SiC) and snail shell particles (SSP) was used to fabricate a hybrid composites. The aluminum matrix composites (AMCs) are prepared with varying weight proportions of SiC particles for 2.5%, 5%, 7.5%, 10%, and 12.5% using vortex casting technique to study the vibration characteristics, hardness, and corrosion behavior of the composites. The vibrational behavior of the composite material is examined by fast Fourier transform (FFT) analysis using the DEWESoft software to obtain the natural frequency of each sample, to compute the damping ratio for each sample, and to obtain the mode shape of the samples. The one which has highest damping ratio is considered to be more resistant to vibration. Hardness is compared using the Brinell hardness. The corrosion tests are conducted under three different environments, namely, marine (3.5% NaCl), industrial (1.5% NaCl), and atmospheric (0.5% NaCl) environments by potentiodynamic polarization technique using the Tafel extrapolation method. Then, the best combination out of the five is selected and the snail shell particles are incorporated into it as an additional reinforcement with the varying weight proportions of 1%, 2%, 3%, and 4%, thereby making it as a hybrid composite. Energy-dispersive spectroscopy (EDS) analysis is carried out to confirm the existence of particulates in the composite material. These samples are again subjected to vibration, hardness, and corrosion tests. The surface morphology of the samples is studied by recording the scanning electron microscopy (SEM) images of the surfaces before and after corrosion.
