A fou-r ball ma hine was used to investigate the tribo log i al behav io rs of SiO nanoparti les used as additive in Liquid Paraffin. The worn surfa es of the steel balls w ere 2 analyzed by s anning ele tron m i ros opy (SEM ) and X-ray photoele tron spe tros opy (XPS ). A s the resul,t SiO2 nanoparti les as additive an in rease the antwi ear ability and load-arrying apa ity of the Liquid Paraffin.Itm ay be attributed to the form ation of a hem i al rea tion boundary film onsisting of SiO and organi ompound. 2 Keywords:nanoparti le;additive;SiO ;antiwear ability;load-arry ing apa ity 2 [ 1] 　 , - , 1　 SiO 2 , , 　　 1。 [ 2 ～5] 。
