Abstract
Continuous microscratch tests on an uncoated and a diamond-like carbon coated CoCrMo alloy were performed in air to evaluate the micro-friction and micro-tribology by utilizing a load and depth sensing instrument. By using a diamond-like carbon coating, the friction coefficient for a small applied load was found to decrease compared to the CoCrMo substrate. The hard diamond-like carbon coating prevents the local plastic yielding of the micro-contacts and the adhesion between the metal/metal surfaces during the microscratch tests. However, the effect of the diamond-like carbon coating on the friction was not seen when the applied load is high.
