This paper deals with the study of the abrasive effect of commercial magnetorheological (MR) fluids on steel material. The tests were performed on a tribometer with a pin-on-plate configuration; the sample was flooded with the examined fluid. The rate of abrasion, caused by MR fluids and hydraulic oil, was compared. The difference among the tested MR fluids has been shown to be minimal and the abrasion is approximately twice as large as when using hydraulic oil. The results are beneficial for the development of MR dampers, a material with a higher resistance against abrasion wear must be used for a hydraulic tube. Furthermore, the testing procedure and test conditions were established and thus this test can be repeated with new materials until the abrasion is not as extensive as that with hydraulic oil.
