Characterization of Size and Antiwear Ability of Molybdenum Disulfide Nanoparticles

摘要

In this paper, the results of a study about using Molybdenum disulfide nanoparticle in base oil, which is used for engine oil production, are presented. The size characterization and morphology of nanoparticles were determined by atomic force microscopy (AFM), scanning electron microscopy (SEM) and X-ray diffractometry (XRD). Dispersion of nanoparticles in base oil was achieved by ultrasonic homogenizer and the antiwear ability was evaluated by four ball test.
