Results show that the wear
rate decreases as the percentage of the nano TiO2 particles
decreases from 0.5% to 4.5%. For example, the weight loss
decreased from 1.7 mg to 0.6 mg when the nano TiO2 particles
decreased from 0.5% to 4.5%. On the other hand the wear rate
of all the investigated samples increased by increasing the
applied load. Severe wear Conditions can be seen through
the rate of the weight loss. The recognized wear behavior is
consistent with the pattern presented by
