Abstract
Nanomaterials, with their unique physicochemical properties, demonstrate promising application prospects in the field of mechanical engineering. As modern industry increasingly demands high-performance mechanical components, traditional materials struggle to meet the stringent requirements of harsh working environments, whereas nanomaterials can significantly enhance the performance of mechanical systems. This study aims to explore the application potential of nanomaterials in mechanical engineering by systematically analyzing their mechanical properties, tribological behavior, and composite modification mechanisms, thereby providing theoretical support for the development of novel mechanical functional materials. Combining experimental testing with numerical simulation, this research focuses on the preparation processes and microstructural evolution of nanoparticle-reinforced me tal matrix composites, revealing the intrinsic relationship between material strengthening mechanisms and wear characteristics at the nanoscale. The results indicate that the addition of an appropriate amount of nanoparticles effectively improves material hardness, wear resistance, and fatigue strength while reducing the friction coefficient. An innovative preparation method for nanocomposites based on in-situ synthesis technology is proposed, achieving uniform dispersion of nanoparticles in the matrix and addressing the aggregation issues commonly encountered in conventional processes. This research not only offers new insights and technical approaches for developing high-performance mechanical components but also lays a solid foundation for promoting the practical application of nanotechnology in the field of mechanical engineering.
