Abstract: Magnetorheological fluid (MRF) will be widely used in many application fields as a new kind smart material. It is very important to know the tribological properties of MRF in order to design a better composition and evaluate the combination properties of MRF. The friction and wear behaviors of Carbonyl Iron-based MRF were investigated on a four-ball machine under three different magnetic fields. The results showed that the friction coefficient of MRF under magnetic field was much higher than that without magnetic field .The friction coefficient of MRF changed along with different strength of magnetic field. The morphology of worn surface was changed from circle or ellipse to irregular rectangle. Worn trace became flat under magnetic field.
