    Abstract

    Ethanolamines are used in tribology as anti-corrosion additives and as cutting fluids in metal working. Goal of the present study was an experimentally based theory of the lubricating properties of ethanolamines from the nano- via the micro- to the macroscopic scale. The different ethanolamine oligomers (monoethanolamine, diethanolamine and triethanolamine) were investigated with three different methods: ball-on-disk tribometer (macroscale), microtribometer (microscale) and atomic force microscopy (nanoscale). In all three experimental methods lubrication is oligomer specific: at the given experimental situation, monoethanolamines prove to be the best lubricants, diethanolamines are less effective, and triethanolamines are the least effective in reducing friction. Force spectroscopy and photoelectron spectroscopy investigations corroborate these results: the smallest pull-off force occurs for monoethanolamines. The explanation for this is that the additives increase the surface energy and therefore the three oligomers with their different numbers of hydroxyl groups have different binding strengths.
