纳米碳化硅改性聚四氟乙烯复合材料的摩擦磨损性能
Friction and Wear Properties of Nano-SiC Modified PTFE Composites
摘要
Abstract
Nano-SiC was treated with different coupling agents, the effect of coupling agent content on tribology properties of PTFE composites was investigated. The worn surface of PTFE composites was examined with a scanning electron microscope (SEM). It showed that hardness and tribology properties of PTFE composites filled with treated nano-SiC were higher than those with untreated nano-SiC, and the titanate (NDZ101)was the most effective among various coupling agents. The wear mass loss and friction coefficient of PTFE composites decreased with increasing coupling agent, however, the effect was inversed when the loading of coupling agent was larger than 1%. SEM micrograph of fracture surface revealed that there was favorable interface bonding between NDZ101 treated nano-SiC and PTFE matrix. The wear mechanism of PTFE composites was also discussed.关键词
