- Abstract:
- Using liquid phase chemical reduction method, nickel acetate was used as the precursor, polyethylene glycol 6000 as modifier, hydrazine hydrate as reducing agent, sodium hydroxide as pH adjuster in the aqueous system, microwave irradiation was introduced to synthesize nickel nanowires with a length of 1~3 μm and a diameter of 30~50 nm. Nickel nanowires were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Nickel nanowires and spherical nano-nickel were added as base oil liquid paraffin (LP) additives to LP, and the friction and wear properties of LP before and after addition were investigated on UMT-II. friction and wear testing machine and M-2000 ring/block friction and wear testing machine, and the surface morphology and surface film element composition and content were analyzed by scanning electron microscope (SEM) and energy spectrometer (EDS). The results show that compared with the base oil LP, the LP after adding nano-nickel forms a self-healing film, which greatly reduces the friction coefficient, obtains relatively flat grinding marks and significantly improves the friction performance of LP. Compared with spherical nickel nanowires, the addition of nickel nanowires can increase the degree to which they improve the lubrication performance of LP.
