/ Tribometry


Tribometry is the study of frictional forces. The GCM has a “pin-on-disk” device to ascertain the wear rate in dry and liquid media. The sample is put on a disk rotating at a given angular speed. A ball fixed to a vertically-moving stem is pressed on the surface under study for a fixed number of disk rotations. The tangential force and vertical forces are measured, and the wear rate and the frictional coefficient can therefore be deducted.


  • Measure the wear rate
  • Measure the frictional coefficient
