The present study is focused on the tribological performance of Molybdenum disulfide (MoS2), and Alumina (Al2O3) used as reinforcement in Al-Si-Mg alloy. By adapting the stir casting route, aluminum matrix composites (AMCs) are manufactured. The process variables such as weight percent of reinforcement i.e., Al2O3 (4,8, 12 and 16 wt. percent ) , and MoS2 (2 and 4 wt. percent), sliding velocity (1 m/s, 1.5 m/s, and 2 m/s), and load (10, 20 and 30 N), on tribological responses are wear rate and coefficient of friction. The experiments are intended to use the Taguchi Orthogonal array (L27). Mechanical properties such as hardness and tensile strength have been evaluated and hybrid metal matrix composites (HMC) have shown significant improvement. Analysis of Variance (ANOVA) revealed wear rate and coefficient of friction decreased with an increase in sliding speed and increased with the applied load. The worn-out, fractured composite surfaces are examined by a scanning electron microscope (SEM). A predominant wear mechanism is observed at low load has a combination of adhesive and abrasive wear, accompanied by high load as adhesive wear. The hybrid composites exhibited improved wear resistance and low friction coefficient as compared to the base alloy.

“…Systematically, in order to produce the FGMs, there are several physical state approaches to achieve the compositional gradient in the composite, which are clas-sified into three separate categories including gas, liquid and solid-based methods, which can be used to physically or chemically obtain tailored properties [51]. Figure 3 shows the three different types of physical states for the production of FGMs.…”

Functionally graded materials (FGMs) are new materials whose properties change gradually in respect to their dimensions. This group of materials shows a tremendous improvement of previously used composite materials. FGM consists of two or more materials whose combination enables the achievement of specified properties in accordance with the desired application. The article gives an overview of different classifications, various fabrication methods and applications of the FGMs. It could also provide insight and perspective for researchers, university students and research and development teams since it has brought together diverse aspects of FGMs. As mentioned in section two, we took all FGMs fabrication methods under consideration, giving the reader an insight into how to make a product while satisfying the conditions of financial and mechanical efficiency. The classification section specifically goes over structures, types of gradients, sizes/scales, state of matter and finishes with the manufacturing processes. Section two deep dives into the fabrication methods used in the FGMs, which are divided into three sub-sections, including gas-based, liquid-based and solid-based. Lastly, various applications of the FGMs in different fields and industries, namely aerospace, energy, medicine, military, manufacturing and eventually other applications, are demonstrated.

Environmentally‐friendly materials are increasingly sought in use of both structural and non‐structural applications. Most of the prominent places, particulates and fibers are exclusively utilized to reinforce polymeric composites, aiming to enhance their strength and provide effective protection against wear. Currently, one of the most pressing issues encountered in current industries are wear and tear, mostly happens during manufacturing and agricultural operations. To overcome this issue, the current study examines into exploring the effects of different weight ratios (0%, 1%, 3%, 5%, 7%, 9% by wt.%) of fly ash (FA) loading on the abrasive characteristics of Interpenetrating Polymer Networks (IPNs) composites strengthened with E‐Glass fibers. Abrasion tests, conducted in accordance with ASTM D99 standard which involves five control parameters: load, FA content, speed, sliding distance, and surface roughness. Experimental design utilized Taguchi's orthogonal array (L25), with opts ANOVA to identify significant control factors. Results indicate that the addition of FA substantially enhances the wear resistance of particulate‐loaded E‐Glass fiber reinforced IPN composites. Moreover, the specific wear rate is significantly influenced by the applied load and FA content. However experimental data suggests that optimal wear behavior for IPN composites occurs under the conditions of 50 N load, 3% FA content, 300 rpm speed, 4000 m sliding distance, and 0.3 μm disc roughness. Further, scanning electron microscopy was also employed to examine microstructural details to better know the micro‐mechanism behavior happens between the particulates with fiber and matrix reinforcement.Highlights Utilization of fly ash significantly enhances composite strength. IPN laminates fabricated with 0%–7% particulate loads. IPN laminates thoroughly evaluated through wear testing. DOE guided experimental design using L25 orthogonal array. SEM analysis reveals superior quality of fly ash‐loaded IPN.
