Popis:	The antiwear performance of the modified nanodiamond (ND) as an additive to commercial oils was studied. The surface modification and ultrasonic treatment allow the introduction of ND into oils without significant agglomeration. The ND in oils displayed a high colloidal stability for prolonged times. Two fractions of ND with average particle sizes of 96 and 270 nm were used. A block-on-ring test setup was used to investigate the wear reduction capability of the additives at various load conditions and friction pairs. The results showed that 0.01 wt% addition of ND improved the antiwear properties of the lubricants and decreased the oil temperature. No significant difference in performance was found between NDs of different size. The wear reduction mechanism was attributed to the formation of a hard and porous layer between the contact surfaces.
