Melt Friction and Pin-on-Disk Devices
Keyword(s):
A melt concept is proposed to explain the tribology of unlubricated metal pin-on-disk sliding at high speeds. A squeeze film model of the melt film is developed which depends on the continually forming melt to give steady-state load support. Expressions are derived for the film thickness, coefficient of friction, and wear. The theory is applied to pin-on-disk data available in the literature. There is good agreement between theory and experiment for the friction coefficient. The results for wear are inconclusive. A significant factor affecting the findings is surface roughness.
