Tribological behavior of firm kaolin against smooth rigid wall during extrusion process
One of the main factors influencing the quality of production shape and energy consumption in an extrusion process is the interaction between the material and the wall. To investigate the tribological behavior of extrudable kaolin and a rigid wall, a tribometer is specifically designed and validated for measuring friction at the kaolin-wall interface. Compared to another tribometer in the literature, this device permits the variation of the normal stresses at the wall/material interface during testing. Finally, the tribological behavior of kaolin friction is determined within a range of velocities from 10−3 m/s to 5.10−2 m/s and a range of normal stress from 120 to 250 kPa.
