摘要

分别在碱液、水、油和干摩擦条件下考察了碳纤维和玻璃纤维填充聚四氟乙烯复合材料的摩擦磨损性能。利用SEM观察了不同介质中磨损面和对摩面的形貌，并探讨了其磨损机理。结果表明，不同介质中摩擦系数的大小关系是μ干>μ水或油>μ碱，磨损率是W水>W干>W碱或油。水、碱和油都不同程度地阻止了转移膜的形成。碱液和油具有很好的冷却与润滑作用，摩擦系数低，磨损小；然而水分子降低了填料和基体的界面粘接强度，造成犁削和磨粒磨损加重。

Abstract

The friction and wear behavior of PTFE composites filled with carbon fiber (CF) and glass fiber (GF) under alkali

water

oil-lubricated and dry lubrication conditions were investigated. The wear mechanisms of the composites under different lubrication conditions were discussed based on the examinations of the worn ring and counterpart ring surfaces by means of SEM. It was found that the relationship of the friction coefficients and wear rate of the CF/PTFE and GF/PTFE composites sliding under different conditions was μ dry>μ water or oil>μ alkali and W water>W dry>W alkali or oil. The transfer onto the counterpart rings was significantly hindered by water

alkali and oil. Owing to the good stability

cooling and boundary lubrication capacity of alkali and oil-lubricated conditions

all PTFE composites filled with CF and GF showed much lower friction coefficients and wear rate. However

the bonding property of the interface was decreased by water. Abrasion and furrow were the main cause of the wear

leading to increasing wear rate of PTFE composites under water-lubricates condition.
