Abstract
FIELD: magnetorheologic materials. SUBSTANCE: magnetorheologic material has liquid medium and magnetically active particles. Particles are modified so that particle surface is completely free from fouling products. The latter are removed from particle surface by treating with abrasive material, chemical treatment, or combination thereof. EFFECT: improved magnetorheologic effect of materials prepared by using particles wherefrom fouling products are removed.
