Abstract
- To enhance the bonding capability of composite ceramic powder and subsequently improve the friction stability of copper-based composite materials, B 4 C-SiC ceramic powder modified at different temperatures was used. The results indicate that elevating the modification temperature of ceramic powder promotes faster growth of particles and enhances inter-particle bonding. The mechanical properties of the copper-based composite material are significantly improved, particularly at 1400 °C, owing to the filling of pores and the particle reinforcement effect of ceramic. Meanwhile, the friction coefficient and wear exhibit a gradual increase, mainly caused by the formation of microasperities from larger ceramic particles and sepiolite, leading to changes in the friction-film and friction mechanism. The primary wear mechanism shifts from abrasive wear (1200 °C-1300 °C-1400 °C) to oxidative wear (1500 °C). [ABSTRACT FROM AUTHOR]
