An effort was being made to incorporate waste bagasse ash (WBA) both in carbonized and uncarbonized form into the formulation of Al6063 matrix-based metal matrix composites (MMC’s) by partially substituting ceramic particles for them. In the process of developing composites, comparative research on carbonized WBA and uncarbonized bagasse powder was carried out in the role of reinforcement. Microstructure investigations revealed that carbonized WBA particles were properly distributed throughout the aluminum-base metal matrix alloy. They also had the appropriate level of wettability. The reinforcement of carbonized WBA particles in AA6063-based matrix material had a maximum tensile strength of 110 MPa and a maximal hardness of 39 BHN when 3.75 wt % of the particles were used. The deterioration in tensile strength (6.25 wt % of WBA) and the appearance of porosity and blowholes can be enumerated by tensile fractography-based scanning electron microscopy (SEM) analysis. The reinforcement of carbonized WBA particles in AA6063-based matrix material was found to have a maximal percent elongation of 14.42% and the highest fracture toughness of 15 Joules when 1.25 wt % of the particles were employed. For AA6063/3.75 wt % carbonized WBA-based MMC’s, the minimum percent porosity was determined to be 5.83, and the minimum thermal expansion was found to be 45 mm3. As the percentage of reinforcement in bagasse-reinforced composites increases, the density of the material, the amount of corrosion loss, and the cost all decrease gradually. The AA6063 matrix, with a composition of 3.75 wt % carbonized WBA-based MMC’s, had satisfactory specific strength and corrosion loss. The AA6063 alloy composite’s microstructure analysis revealed that carbonized WBA enhanced the material’s mechanical characteristics, contributing to its excellent mechanical capabilities. The results of the corrosion test showed that carbonized WBA-reinforced composites exhibited reduced weight loss due to corrosion, whereas uncarbonized bagasse powder was an inappropriate reinforcement. The SEM analysis of AA6063 alloy/3.75 wt % carbonized WBA ash reinforcement-based MMC’s exposed to a 3.5 wt % NaCl solution has exhibited the development of corrosion pits as a result of localized attack by the corrosive environment. The thermal expansion test showed that the composite with uncarbonized bagasse powder as reinforcement have a high shrinkage rate in comparison with the composite with 3.75 wt %. The composite’s mechanical characteristics and thermal stability were enhanced by the presence of hard phases like SiO2, Al2O3, Fe2O3, CaO, and MgO, as revealed by X-ray diffraction analysis. This made it suitable for use in a variety of applications.

“…Sustainable and biodegradable waste materials have been experimented upon to assess their potential as effective reinforcing materials in Al matrix composites. Results show they positively impact the resulting composite's properties, industrial relevance and consumer applications [11][12][13][14]. Corrosion resistance of Al matrix composites (with respect to reinforcing materials) is an important factor in material selection of composite for application [15][16][17].…”

Particulates of cow bone (CB) and coconut shell (CS) were infused within the microstructure of 1170 aluminium alloy and studied for their influence on the corrosion resistance of the resulting aluminium matrix composites in 3.5% NaCl, 0.05 M H2SO4 and 3.5% NaCl/0.05 M H2SO4 solution by weight loss method. Corrosion rate data shows CB and CS significantly influenced the electrochemical properties of the composite. Protection performance data at 336 h of exposure shows CB and CS particulate significantly reduced the corrosion resistance of the aluminium alloy at all weight compositions in 3.5% NaCl solution. In 0.05% H2SO4 solution, CB improved the corrosion resistance of the composite at 5% - 15% weight composition (37.8%, 23.22% and 23.22%), while CS improved the corrosion resistance at 10% and 20% weight composition (37.65% and 28.52%). The corresponding values for CB in 3.5% NaCl/0.05 M H2SO4 solution occurred at 5% - 15% weight composition (34.26, 31.71% and 22.68%) while for CS it occurred at 10 and 15% weight composition (40.52% and 46.05%). Data from ANOVA statistical tool shows particulate weight composition and exposure time are both relevant determinant variables (greater than the theoretical significance factor) influencing the protection performance outputs of CB and CS with values ranging between 41.82% to 92.5% for weight composition and 5.68% and 53.03% for exposure time. Standard deviation data for CB particulate varied minimally only at 20% weight composition in 3.5% NaCl solution. The corresponding data at other CB weight compositions and for coconut shell at all weight compositions varied significantly due to thermodynamic instability.In 0.05 M H2SO4 and 3.5% NaCl/0.05 M H2SO4 solutions, all standard deviation values for CB and CS particulates (excluding CB at 29% weight composition) at all weight compositions vary minimally from the mean data signifying thermodynamic stability of the electrochemical reactions on the composite surfaces with respect to exposure time. The proportion of data above 20% protection performance for CB and CS particulates in 3.5% NaCl solution is 0% at margins of error of 0%. The corresponding values in 0.05 M H2SO4 solution are 15.18% and 15.32% at margins of error of 40% and 43% while the values from 3.5% NaCl/0.05 M H2SO4 solution are 14.78% and 15.5% at margins of error of 35% and 50%.
