In situ synthesis and tribological behavior of copper nanopieces in liquid paraffin as additive in Mobil 1 5W- 30 lubricating oil

摘要

To synthesize morphology- controlled nano- copper with excellent lubrication properties as lubricant's additive, chemical reduction synthesis method was used coalescing in situ via liquid paraffin as resolvent and modification with polyethylene glycol (PEG-2000). The as- prepared Cu nanopieces with 35.59 nm average length and 21.03 nm average width were characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM).
