WebBesides, the friction coefficient decreased with increasing sliding velocity and normal loads, due to the rolling effect of the physisorbed C60 molecules. The Langmuir-Blodgett (LB) technique15,16 and selfassembly method17-21 are known as the novel alternative approaches of preparing C60 films with good tribological properties. WebMay 1, 1996 · The friction of diamond is low, which makes it attractive. However, natural diamond shows anisotropic effects and also coefficients of friction which depend on the environment. Termination of dangling bonds by hydrogen or other adsorbates gives diamond its low friction. Moisture can reduce the friction even further under certain …
