“…Across the whole immersion time period, the sample for which a 1100 rpm tool rotational speed was used attained an excellent corrosion resistance. Microstructure alteration increases the corrosion resistance, suggesting that tool speed is the major factor in FSP [23][24][25][26][27][28]. The highest corrosion rate was obtained at the start of the test.…”

A lightweight, highly corrosive resistant, and high-strength wrought alloy in the alumi-num family is the Aluminium 8006 alloy. The AA8006 alloy can be formed, welded, and adhesively bonded. However, the recommended welding methods such as laser, TIG (Tungsten Inert Gas welding), and ultrasonic are more costly. This investigation aims to reduce the cost of welding with-out compromising joint quality by means of friction stir welding. The aluminum alloy-friendly re-inforcement agent zirconia is utilized as particles during the weld to improve the performance of the newly identified material AA8006 alloy in friction stir welding (FSW). The objectives of this research are to identify the level of process parameters for the friction stir welding of AA8006 to reduce the variability by the trial-and-error experimental method, thereby reducing the number of samples needing to be characterized to optimize the process parameters. To enhance the quality of the weld, the friction stir processing concept will be adapted with zirconia reinforcement during welding. The friction stir-processed samples were investigated regarding their mechanical proper-ties such as tensile strength and Vickers microhardness. The welded samples were included in the corrosion testing to ensure that no foreign corrosive elements were included during the welding. The quality of the weld was investigated in terms of its surface morphology, including aspects such as the dispersion of reinforced particles on the welded area, the incorporation of foreign elements during the weld, micro defects or damage, and other notable changes through scanning electron microscopy analysis. The process of 3D profilometry was employed to perform optical microscopy investigation on the specimens inspected to ensure their surface quality and finish. Based on the outcomes, the optimal process parameters are suggested. Future directions for further investigation are highlighted.

The utilization of agro waste as reinforcement in metal matrix composites (MMCs) has sparked interest regarding its feasibility and sustainability in engineering practices. Compared to synthetic reinforcements, its efficacy as a potentially cost-effective and environmentally friendly alternative has been explored by diverse studies. This review critically examines existing literature on agro waste-based reinforced MMCs, evaluating experimental findings on mechanical, tribological, density, and corrosion performance from a sustainable engineering perspective. Furthermore, it explores the innovative strategy of employing multi-component metal matrix composites to fabricate composites with improved performance attributes. The utilization of multi-component reinforcements has the capability to tackle issues like the challenge of disproportionate reduction in ductility and toughness peculiar to monolithic and hybrid MMCs. Despite promising results in some studies, numerous unexplored research areas and gaps remain, emphasizing the need for further investigation to provide valuable guidance for future research and development of agro waste in sustainable engineering applications.

Aluminum matrix composites (AMCs) have been extensively studied primarily due to higher strength-to-weight ratio, lower cost, and higher wear resistance properties. However, increasing demand for economical and energy-efficient materials in the automotive, aerospace and other applications is tailoring research area in the agro-based composite materials. Therefore, the aim of this systematic review work is to study the influence of agro-based reinforcements on the tribological and mechanical properties of AMC's processed by various techniques. It was observed that the processing conditions can be designed to obtain uniform structures and better properties AMCs. The agro-waste reinforcement materials, such as rice husk ash, bamboo stem ash, coconut and shell ash can result in a reduction in the density of AMC's without compromising mechanical properties. Moreover, the efficient utilization of the agro-waste leads to a decrease in manufacturing cost and prevents environmental pollution, hence, can be considered as a sustainable material. The state-of-the-art revealed that the agro-based reinforcements do not form brittle composites, as in the case of ceramic reinforced composites. Hence, the study concludes that the agrobased AMCs have great potential to act as a replacement for costly and environmentally hazardous ceramic reinforced-AMCs which can especially be used in various automotive applications that demand higher strength-to-weight ratio, lower cost, and higher wear resistance.
