Abstract
A magnetorheological fluid is provided having a reduced coefficient of friction and favorable settling characteristics. The fluid contains magnetically responsive particles, a carrier fluid, and an amine oleate salt.
Claims18
A magnetorheological fluid comprising magnetically responsive particles having an average particle diameter size of about 1 micrometers (μm) to 1000 μm, a carrier fluid, a friction reducing agent comprising an amine oleate salt that comprises at least one of a diamine dioleate or a triamine dioleate, an organoclay, micron or sub-micron sized molybdenum disulfide, and one or both of an organomolybdenum and a thiophosphorous compound.
A magnetorheological fluid consisting of magnetically responsive particles having an average particle diameter size of about 1.0 micrometers (μm) to 1000 μm, a carrier fluid, an amine salt of a carboxylic acid, an organoclay, one or both of an organomolybdenum and a thiophosphorous compound, and optionally micron or sub-micron sized molybdenum disulfide.
