Abstract
In order to know the running-in process for ultra low friction of CNx sliding against Si3N4 balls in N2, the effect of surface roughness of balls on friction coefficient was investigated. As results, it was shown that friction coefficient for all of Si3N4 balls decreased with sliding cycles and reached to the specific minimum values less than 0.05. For friction coefficient less than 0.01, smooth surface of ball with 30 nm Ry as initial surface roughness was necessary. Smooth surfaces of CNx coating and Si3N4 ball after running-in provide ultra low friction after the transfer of tiny amount of CNx to Si3N4 ball and the generating of thin and uniform transfer film on balls.
