Study on Tribological Performance of Nano Particle Reinforced Metal Matrix Composite

Abstract

Metal matrix composites (MMCs) have gained significant attention in various engineering applications due to their enhanced mechanical and tribological properties. In recent years, the incorporation of nanoparticles into the metal matrix has emerged as a promising approach to further improve the performance of MMCs. This study aims to investigate the tribological performance of nanoparticle-reinforced metal matrix composites. To evaluate the tribological performance, a series of experiments are conducted using a pin-on-disk tribometer under controlled test conditions. The tribological parameters, such as friction coefficient and wear rate, are measured and compared between the nanoparticle-reinforced MMCs and the conventional metal matrix composites. The influence of factors such as load, sliding speed, and temperature on the tribological behavior is also investigated. In addition to experimental investigations, characterization techniques such as scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) are employed to analyze the worn surfaces and understand the wear mechanisms. The microstructural analysis provides insights into the interaction between the nanoparticles and the metal matrix, as well as their role in improving the tribological performance. The results of this study will contribute to the understanding of the tribological behavior of nanoparticle-reinforced metal matrix composites. The findings will help in optimizing the composition and processing parameters to achieve superior tribological properties in various engineering applications, including automotive, aerospace, and manufacturing industries.
