Abstract
A lubricant, a friction pair having the lubricant and a method for controlling COF between the friction pair are provided. The friction pair includes a first friction part (1) and a second friction part (2). Firstly a lubricant (4) is provided between the first and second friction parts (1, 2). Then a potential is applied on the first friction part (1) via the lubricant (4). And COF is controlled by controlling the potential. The lubricant (4) contains propylene carbonate and a surfactant.
Claims6

- providing a lubricant between the first and second friction parts;
- applying a potential on the first friction part and adjusting the potential of the first friction part by an electrode system, in which the first friction part is used as a working electrode;
- and
- adjusting the friction coefficient by adjusting the potential of the first friction part,
- wherein the lubricant comprises propylene carbonate as a solvent and a surfactant,
- wherein the lubricant is a solution of sodium dodecyl sulfate in propylene carbonate, and the sodium dodecyl sulfate has a concentration selected from:
- 0.1 mM, 0.5 mM, 1 mM and 2 mM.
