Abstract

In this paper, the antiwear and antifriction performance of MoS2 nanoparticle in castor oil was studied. The ball-on-disc tests were performed for different concentrations of MoS2 nanoparticle. Coefficient of friction, wear loss, and worn surface morphology were investigated. The results show that MoS2 nanoparticle could reduce the possibility of asperities direct contact, resulting in the reduction of the coefficient of friction and adhesive wear. However, MoS2 nanoparticle in excessive concentration could agglomerate into large particles, playing the role of an abrasive particle, which reduces the beneficial effects of MoS2 nanoparticle.
