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.
期刊介绍：
Tribology Letters is devoted to the development of the science of tribology and its applications, particularly focusing on publishing high-quality papers at the forefront of tribological science and that address the fundamentals of friction, lubrication, wear, or adhesion. The journal facilitates communication and exchange of seminal ideas among thousands of practitioners who are engaged worldwide in the pursuit of tribology-based science and technology.
