Research Abstract

Friction and wear behavior of PTFE-based composite was evaluated under various experimental conditions. The obtained results were as follows :
1. At the sliding velocity above 10m/s, friction coefficient was constant at 〜0.3. The wear rate of the composite was of the order of 10ィイD1-6ィエD1(mmィイD13ィエD1/Nm). Thus the composite did not transit to a catastrophic wear such as seizure under the severe sliding condition. After friction, matrix of the composite was covered with much fine and brown oxide particles. Glass fibers were polished and became flat. It is suggested that these embedded oxide particles and glass fiber fillers strengthened the composite surface.
2. Friction and wear of PTFE-based composite was not strongly dependent on the mating surface roughness. Even if the surface roughness became larger than the oil film thickness, mixed lubrication persisted. Further, mixed lubrication was maintained at high temperature of 100-150℃ and friction coefficient was 0.02-0.04. Thus PTFE-based composite had a high capacity for maintaining mixed lubrication.
3. As the amount of wear debris generated in the wear test was too small, wear debris was not detected clearly by laser diffraction particle size analyzer. Size of detected wear debris was small and 0.4μm. Thus it was concluded that lubricated wear of PTFE-based composite was very small.
From above results, it was concluded that the PTFE-based composite had a high potential for the practical use as the maintenance-free sliding bearing.
