A magnetorheological fluid that includes magnetic-responsive particles, a carrier fluid and a phosphorus additive. The magnetorheological fluid does not include an organomolybdenum, a thiophosphorus additive or a thiocarbamate additive.

Magnetorheological fluid

A magnetorheological fluid that includes magnetic-responsive particles, a carrier fluid and an organomolybdenum. The organomolybdenum preferably includes at least one molybdenum atom bonded to at least one organic moiety wherein the organic moiety can be derived from a precursor selected from the group consisting of a saturated or unsaturated hydrocarbon, an aromatic hydrocarbon, an oxygen-containing compound, a nitrogen-containing compound and a compound containing more than one functional group.

Organomolybdenum-containing magnetorheological fluid

A magnetorheological material containing a carrier fluid, a particle component and a thixotropic additive to provide stability against particle settling. The thixotropic additive can be a hydrogen-bonding thixotropic agent, a polymer-modified metal oxide, or a mixture thereof. The utilization of a thixotropic additive creates a thixotropic network which is unusually effective at minimizing particle settling in a magnetorheological material.
