本文的目的是找出磨粒特性、摩擦系数和磨损率之间的关系，以确定磨损机理。空压机活塞环是由聚四氟乙烯(PTFE)制成的，但其磨损率很高，必须进行强化。本文采用现象学方法研究了三种聚四氟乙烯(纯聚四氟乙烯和填充玻璃纤维和碳石墨)与片状灰铸铁的接触温度对接触的影响。
The aim of this article is to find correlations between the characteristics of the wear particles, the coefficients of friction and the wear rates in order to determine wear mechanisms. In the air compressors, piston rings are made of polytetrafluoroethylene (PTFE) but its wear rate is very high and it must be reinforced. This work is devoted to the influence of temperature with three types of PTFE (pure and filled with glass fibre and carbographite) against flake grey cast iron thanks to a phenomenological study of the contact.
