Abstract
This paper discusses the application of nanomaterials in the surface modification of mechanical parts. Firstly, it expounds the unique characteristics of nanomaterials, including size effect, specific surface area increase, quantum effect and controllability, which provide a theoretical basis for the application of nanomaterials in the modified field. Subsequently, the paper analyzes the three main principles of nanomaterials modified mechanical parts surface: physical modification (such as coating enhancement, surface roughness change), chemical modification (such as chemical reaction, surface bonding) and mechanical modification (such as strengthening mechanism, stress distribution), reveals the potential of nanomaterials in improving the performance of mechanical parts. This paper introduces various applications of nanomaterials in the surface modification of mechanical parts, including nano-coating modification, nano-osmotic modification, nanosurface alloying modification and nanocomposite modification technology. These applications not only improve the wear resistance, corrosion resistance and hardness of mechanical parts, but also prolong their service life, demonstrating the broad prospect of nanomaterials modification technology. The surface of modified mechanical parts of nanomaterials also faces a series of problems, such as the stability and dispersion of nanomaterials, the complexity and cost of modification process, the evaluation and verification of modification effect, and the safety and environmental protection considerations. In view of these problems, this paper proposes the corresponding improvement measures in chapter 5, including optimizing the preparation and dispersion technology of nanomaterials, simplifying the modification process to reduce the cost, establishing a perfect performance evaluation and verification system, and strengthening the safety and environmental protection management.
