Influence of different types of carbon nanoflakes on tribological and rheological properties of plastic lubricants

The tribological and rheological characteristics of three industrially produced greases and a model lubricant (medical vaseline) doped with new carbon nanoflakes additives (few layer graphite nanofragments, LGF and their nitrogen-containing analog, N-LGF) have been studied. It is shown that the modification of carbon structure with heteroatoms can significantly reduce friction coefficient under certain loads. The results obtained in this work demonstrate the prospects for further study and the use of modified carbon nanomaterials.
