Synthesis and Tribological Properties of MoSe₂/C and MoSe₂ Nanoflakes

Abstract:

The inorganic materials（MoSe₂/C) and MoSe2 were synthesized via solid-state reaction methods and characterized by a series of techniques. The growth process of the products was discussed on the basis of the experimental facts. The tribological properties of MoSe₂/C and MoSe₂ as additives in 150bn basic oil were investigated by UMT-2 multispecimen tribotester. Under the determinate conditions, the friction coefficient of the basic oil containing MoSe₂/C (or MoSe₂) was lower than that of the basic oil. Moreover, the tribological property of the basic oil with the MoSe₂/C was better than that with MoSe₂ nanoflakes. A combination of sliding friction, stable tribofilm and fill in-repair mechanisms on the rubbing surface could explain the good friction and wear properties of MoSe₂/C and MoSe₂ as additives.
