Dept. of Mechanical Engineering, SungKyunKwan University*Neoenbiz.Co.(Received August 16, 2011; Revised October 20, 2011; Accepted October 23, 2011)Abstract − Nanodiamond was dispersed in paraffin liquid oil to investigate the effects of nanodiamond at themarginally lubricated condition. Scuffing test and immediate loading sliding wear test were conducted using thefabricated nanodiamond oil. As a result, dispersion of nanodiamond in oil leads to increase in scuffing life, andnanodiamond contents affects the scuffing life. In case of immediate loading sliding wear test, the result was dif-ferent according to hardness of specimen. If hardness of specimen was low, abrasion of nanodiamond occurredactively. If hardness of specimen was increased, however, nanodiamond can act as a spacer or rolling betweencontacting surfaces.Keywords − nanodiamond(), paraffin liquid(  ), scuffing life( ), hardness(), marginally lubricated condition()
