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.

Claims (1)

Магнитореологический материал, содержащий жидкость-носитель и магнитно-активные частицы. Частицы модифицируют таким образом, что поверхность частицы является полностью свободной от продуктов загрязнения. Продукты загрязнения удаляют с поверхности частицы с помощью обработки абразивом, химической обработки или их комбинации. Магнитореологические материалы, приготовленные с использованием частиц, с которых удаляются продукты загрязнения, проявляют значительно большие магнитореологические эффекты.Magnetorheological material containing carrier fluid and magnetically active particles. Particles are modified in such a way that the surface of the particle is completely free of contamination products. Pollution products are removed from the surface of the particles by abrasive treatment, chemical treatment, or a combination thereof. Magnetorheological materials prepared using particles from which contaminants are removed exhibit significantly greater magnetorheological effects.
