Abstract

A systematic study combined experiment and temperature-related simulation has been conducted to evaluate the wear and friction performance of poly-ether–ether–ketone (PEEK) and preliminary explore the feasibility of PEEK as the reciprocating transmission component material. The reciprocating sliding test was carried out with PEEK–PEEK surface contacting tribo-pair under dry conditions at room temperature. The temperature-dependent wear rate was calibrated into the simulation to predict the wear behavior of PEEK. The results showed strong correlations between its friction and wear behaviors and pressure, velocity as well as temperature increase caused by friction. With the increase of velocity and pressure, the friction coefficient of PEEK decreased. An empirical formula of friction coefficient considering both velocity and pressure for PEEK was first proposed. As the velocity and pressure increased, the wear mechanism changed and wear intensified. Pressure had a greater influence on wear rate than velocity due to friction heat.
