摘要

这项工作表明，核壳结构有望满足离合器高摩擦和低磨损的要求。文章将两种核壳颗粒添加到铜基摩擦材料中进行摩擦学测试。结果表明，随着浓度的增加，摩擦系数呈现先增大（从 0.13 到 0.67）后减小（从 0.67 到 0.57）的趋势。在相同浓度下，碳包铜（Cu@C）摩擦材料的 COF 比碳包铜（C@Cu）摩擦材料高 0.4，但磨损率却低 43.1%。两种材料都表现出很高的 COF，但由于摩擦膜的成分不同，它们的磨损行为也不同。

Tribological and Wear Properties of Cu-Based Composite Reinforced by Core–Shell Structure in Multi-disk Clutch

This work indicates that the core–shell structure is expected to meet the requirements of high friction and low wear for clutches. In the article, two types of core–shell particles are added to Cu-based friction materials for tribological testing. The results showed that as the concentration increased, the coefficient of friction showed a trend of first increasing (from 0.13 to 0.67) and then decreasing (from 0.67 to 0.57). At the same concentration, the COF of carbon coated copper (Cu@C) friction material is 0.4 higher than that of copper coated carbon (C@Cu) friction material, but the wear rate is 43.1% lower. Both materials exhibit high COF but their wear behavior are different due to the distinct components of the friction film.
