| Abstract | ||||
| Nowadays, researchers are mostly drawn to green synthesis methods for nanoparticles because of their economic viability and environmental friendliness. Compared to the eco-green approaches developed in this work, traditional synthesis methods have one significant drawback: an extended reaction time. This work presents a novel method for producing silver nanoparticles (AgNPs), which is then used to reinforce Al6061 alloy matrix. For a novel microwave assisted green AgNPs synthesis optimization, many trials have been made to speed up the reaction time. The approach involves microwave-irradiating extracts of Aloe vera leaves. The produced nanoparticles were used to investigate tribological characteristics of the reinforced Al6061matrix composition. XRD analysis demonstrated improvements in particle sizes, particularly when utilizing the microwave-assisted approach, and confirmed the creation of AgNPs in the newly introduced green method. Indexing, inter atomic spacing, and specific surface area, were analyzed. Three samples, 0, 1, and 2 wt. % AgNPs contents, were manufactured using powder metallurgical technique for the purpose of investigating tribological enhancements. A dry wear test was performed monitoring many test parameters such as temperature, friction force, and humidity. The coefficient of friction (COF) and weight loss rates were evaluated in relation to the tribological properties. At different sliding speeds, the relationship between weight loss rates and AgNPs contents was examined, and substantial improved behavior was perceived. | ||||
