Abstract
Aqueous solutions of three tetraalkylammonium thiomolybdates (R4N)2MoS4 (R = methyl, propyl or hydrogen) were prepared and their tribological performance was tested using a pin-on-disc tribometer on a steel-aluminum contact. Tests were performed at the same conditions of load, entrainment speed, sliding distance, temperature, and concentration of the solution to compare the activity (lubrication effect) of the thiomolybdates. Tetralkylammonium thiomolybdates exhibited good friction and wear reduction properties in water-based systems. The surface examination of the rubbing zone indicated that a tribofilm containing molybdenum disulfide is formed on the rubbing surfaces non-homogeneously during the sliding process. 3. Under friction conditions, tetraalkylammonium thiomolybdates was transformed to molybdenum disulfide by tribo-reduction influencing friction and wear performance. This is an abstract of a paper presented at the 2006 STLE Annual Meeting Conference Proceedings (TELUS Convention Centre Calgary, Alberta, Canada 5/7-11/2006).
