摘      要：Nanodiamond particles(NDPs)have been considered as a potential lubricant additive to various tribological applications,such as water lubrication *** this study,the tribological properties of silicon carbide(SiC)lubricated by NDPs dispersed in water are investigated utilizing the ball-on-disk *** is found that the slight addition of NDP to water(i.e.,0.001 wt%)can distinctly accelerate the running-in process,which is necessary to achieve a friction coefficient(μ)as low as *** study also discusses two NDP functional terminations—hydroxyl and *** is demonstrated that the use of carboxyl-terminated NDP over a wide range of concentration(0.001 wt%-1 wt%)yields a low friction *** contrast,the ideal effective concentration of hydroxyl-terminated NDP is considerably limited because agglomeration in this material is more probable to occur than in the ***,when utilizing NDPs,the input friction energy(P_(in),defined as the product of sliding speed and applied load)is found to have an essential *** sliding tests were implemented at various P_(in) values(50-1,500 mW)using carboxyl-terminated water-dispersed *** was observed that theμand wear decreased with increasing P_(in) when 200 mWP_(in)1,500 ***,when P_(in)200 mW,low friction with high wear occurs compared with the resulting friction and wear when pure water is used.
