摘要：

Magneto-rheological suspensions (MRS) have been obtained by mean of ultrasonic dispersion of Fe-Cr-P amorphous and quasi-amorphous ferromagnetic powders in a polymeric solution. Ferromagnetic powders have more than 80% amorphous phase and the average dimension smaller than 1 mu m. The resulting suspensions present interesting magnetic and magneto-rheological properties, as well as good structural stability of powder over time and temperature. The suspension has also a good gravitational stability for periods of time longer than one week. (C) 1999 Elsevier Science B.V. All rights reserved.
