TRIBOLOGICAL BEHAVIORS OF ZnSe NANOPLATES AS LUBRICANT ADDITIVE

摘要

The ZnSe nanoplates were synthesized by a facile and effective hydrothermal method. The morp hology and structure of the ZnSe nanoplates were characterized by powder X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicated that ZnSe nanoplates with diameters of 200-300 nm and average thickness of 100 nm. Th e performance of the ZnSe nanoplates as a base oil additive was investigated by employing a UMT-2 ball-on-disc tribotester. Under the determinate conditions, the friction coefficient of the base oil containing 1.5wt% ZnSe nanoplates was lower than that of the base oil. The improved tribological properties of ZnSe as additives could be attributed to the stable tribofilm on the rubbing surface.
