Abstract
With the rapid development of modern industrial technology, the performance requirements of mechanical parts are constantly improved. The traditional surface treatment technology of mechanical parts has been difficult to meet the growing demand of wear resistance, corrosion resistance, fatigue resistance and other performance requirements. As an emerging material system, nanomaterials provide completely new ideas and methods for the surface modification of mechanical parts with their unique physical and chemical properties. The application of nanomaterials on the surface of mechanical parts can significantly improve the hardness, wear resistance, friction performance, surface finish and accuracy of parts, so as to prolong the service life of parts and improve the overall performance of mechanical equipment. Therefore, this study focuses on the application of nanomaterials in the surface modification of mechanical parts, and aims to explore the improvement effects and challenges of nanomaterials on the performance of mechanical parts. By reviewing the research status at home and abroad, this paper expounds the definition, classification and characteristics of nanomaterials and their application principles in mechanical engineering. The application advantages of nanomaterials in improving the surface hardness and wear resistance of mechanical parts, improving the friction performance, and improving the surface finish and accuracy are mainly analyzed. At the same time, this paper also points out the challenges of dispersion stability, coating uniformity and long-term stability of nanomaterials in the surface modification process of mechanical parts, and puts forward the corresponding technical approaches and countermeasures. This study not only provides theoretical support for the application of nanomaterials in the surface modification of mechanical parts, but also provides a useful reference for subsequent research and practice.
