Specific wear rate (pin-on-disk)
Specific wear rate from a pin-on-disk test, derived from the worn volume, normal load and sliding distance (Archard-type wear coefficient).
Worn volume, V2.5132741228718344e-20 mm³
Specific wear rate, k4.6542113386515456e-27 mm³/N·m
Method & references
- Specific wear rate k = V / (F · s) from a pin-on-disk test.
- Worn volume from the spherical-cap scar geometry.
