The Effect of WS2 Powder Added Lubricant on Friction and Wear of Tetrahedral Amorphous Carbon Coating Films
Source abstract
Abstract
The influence of nanopowder on the tribological properties of ta-C films were examined under the lubrication condition. The addition of the tungsten disulphide, WS2 nanopowder in the synthetic oil, polyalpha- olefin, PAO4 was used as the base lubricant in this experiment. The weight percentages of the additive used are 0, 3.0, 4.0, and 5.0 wt % to understand the concentration effect on the tribological behavior of ta- C films in this study. For the sliding test, the result has shown it is not much different in the friction coefficient results for all cases. Whereas, the wear rate result has shown the obvious trend of which the weight percentage of additives changes the wear resistivity. In this study, 3.0 wt % shows the lower wear rate result at 0.1494 × 10–6; 0.1819 × 10–6 mm3/mN for 4.0 and 5.0 wt % shows the highest wear rate result at 0.2393 × 10–6 mm3/mN. These results were due to the changes in surface roughness due to the different amounts of the additive that have been added.
