Abstract
This paper deeply explores the friction and wear behavior and lubrication mechanism of me tal materials, aiming to provide theoretical support for reducing the friction loss of me tal materials in practical applications, improving equipment efficiency, and extending service life. The research background section elaborates on the impact of friction and wear on the properties and service life of me tal materials, as well as the key role of lubrication mechanisms in reducing friction and wear. The paper first analyzed the mechanical properties of me tal surfaces in contact, explored the energy dissipation mechanism during friction, and classified and characterized the wear forms, laying a theoretical foundation for a deeper understanding of the friction and wear behavior of me tal materials. Subsequently, the paper elaborated on the friction characteristics under boundary lubrication, fluid dynamic pressure lubrication, and mixed lubrication states, constructed corresponding mathematical models, and revealed the mechanism of lubrication. In addition, the paper also conducted in-depth research on the synergistic effect of friction and wear and lubrication mechanisms, and explored the influence of factors such as surface texture, material hardness, and temperature on lubrication performance. By combining theory with experiments, it was revealed how these factors work together to affect the friction lubrication coupling behavior of me tal materials. This paper not only deepens the understanding of the friction and wear behavior and lubrication mechanism of me tal materials, but also provides scientific basis and theoretical guidance for the development of new wear-resistant and anti friction materials, as well as the optimization of existing lubrication technologies.
