MoS2 hollow spheres with an average diameter of 165 nm were prepared from Na2MoO4 and CH3CSNH2 at 82 degrees C. A simple method was used to obtain smaller hollow spheres (70 nm) without any complicated step, except for the addition of TiO2. The tribological properties of MOS2/TiO2 in rapeseed oil were studied using a four-ball tribometer under 350 N at 0.383 m/s. The effects of load and sliding velocity Were also investigated. Wear was significantly alleviated by the produced lubricating film as lubricated with MoS2/TiO2, which was composed of MOO3, Fe2O3, Fe-2(SO4)(3), TiO2 (trace), and carbon-containing compounds. The tribological properties were also improved because of the decrease in the size of MoS2 and the synergistic effect between MOS2 and TiO2. (C) 2014 Elsevier Ltd. All rights reserved.
