Özet
In this study, the effect of sliding velocity, bearing pressure and temperature on friction and wear of PA66 (Polyamide 66), PA66 + 18% PTFE (Polyamide 66 + 18% Polytetrafluoroethylene) and PA66 + 20% GFR + 25% PTFE (Polyamide 66 + 20% glass fiber + 25% Polytetrafluoroethylene) journal bearings were examined at ambient conditions. The results of experiments are presented in graphics which proves that friction coefficients, contact temperatures and wear rates are affected by forming film, increasing temperature, pressure and velocities depending on GFR and PTFE mechanical properties. There are many factors and their widely fluctuation characters on the polymer friction and wear behaviors. The best wear behavior was seen at the PA66 + 20% GFR + 25% PTFE journal bearing.
