| Popis: | This paper presents the enhancement of thermophysical and tribological properties of oil soluble Ni-promoted ultrathin MoS2 nanocomposites blended with gear oil (SAE 75 W). The Ni-promoted ultrathin MoS2 namely Ni-MoS2 nanosheets was exfoliated chemically using ultrasonication and simple reflux techniques. The as-synthesized additives blended with gear oil (i.e., 0.5 wt% of micro MoS2, MoS2 nanosheets and Ni-MoS2 nanosheets) were tested for their thermophysical and tribological properties by using four ball wear tester according to ASTM D2783 standard. The obtained thermophysical and tribological characteristics reveals that the synergetic interaction of Ni and MoS2 nanosheets have better dispersibility and more suitable lubricant additive for extreme pressure region. Thus, the above research enriches the tribological phenomena of transmission elements in the mechanical industry. |
