Research of the antifrictional properties of MoS2 coatings at high temperatures.

In this paper, the influence of temperatures on the tribological properties of molybdenum disulfide-based antifriction solid lubricant coating is researched. The analysis of molybdenum disulfide solid lubricants tests with additives at room temperature and 150 °C is given, the temperature resistance of coatings is determined. It is shown that the coating with graphite in the composition at room temperature has a combination of low friction coefficient and high life time. The kinetics of changes in the friction coefficient with increasing temperature over time has been studied. It is shown that the coating with polytetrafluoroethylene in the composition has the lowest coefficient of friction under the conditions under study. [ABSTRACT FROM AUTHOR]
