Study on preparation methods of copper-based composites
Abstract
Copper matrix composites are generally used as friction disc materials of the water pump clutch due to their excellent mechanical properties, but they also experience severe wear and relative slip between the friction disc and the impeller ring at a high velocity. To investigate the influence of the different structures of the composite on wear performance, this paper discussed the copper-based composites with three process methods, by contrast, the process method of low-pressure preloading and sintering, then perform a high-pressure could effectively improve the densification, hardness and wear resistance.
