| 英文摘要 | This paper reports the tribological behavior of caco3 nanoparticles as a green additive in poly-alphaolefin (pao) base oil under variable applied load, sliding speed, sliding duration, and temperature. the tribological properties and the electrical contact resistance between the tribo-pairs lubricated with pao alone, and pao containing caco3 nanoparticles, were determined using an optimol-srv 4 oscillating friction and wear tester (srv). the morphology and wear volume of the worn scar were measured simultaneously using a surface profilometer. the results showed that caco3 nanciparticles can dramatically improve the load-carrying capacity, as well as the anti-wear and friction-reduction properties of a pao base oil. in addition, higher applied load, moderate frequency, longer duration time, and lower temperatures are beneficial to the deposition of caco3 nanoparticles accumulating on rubbing surfaces. x-ray photoelectron spectroscopy (xps) reveals a boundary film composed of caco3, cao, iron oxide, and some organic compounds on the worn surfaces.
