Influence of Normal Loads and Sliding Velocities on Friction Properties of Engineering Plastics Sliding against Rough Counterfaces

Influence of Normal Loads and Sliding Velocities on Friction Properties of Engineering Plastics Sliding against Rough Counterfaces

Friction properties of plastic materials are very important under dry sliding contact conditions for bearing applications. In the present research, friction properties of engineering plastics such as polytetrafluoroethylene (PTFE) and nylon are investigated under dry sliding contact conditions. In t...
