Friction measurement on Ni-Hard 4 during high pressure
Friction has been measured during crushing of silica sand by Ni-Hard 4 in a high pressure shear cell. It has been found that under the test conditions considered, the friction coefficient first increases with the sliding distance. However, it asymptotically approaches a stable level of about 0.4–0.6.
