摘　　要：从磁流体应用于润滑的特点出发,对制备出的锰锌铁氧体磁性润滑液在四球摩擦磨损试验机上进行了摩擦学性能测试,记录了在不同电压下的摩擦系数,在显微镜下观察磨斑直径,并对结果进行分析。This paper mainly talked about experiments on the terminological properties of the prepared Ferrofluid MnZnFe2O4 in the four-ball tribological testing machine ,which was started from the characters of magnetofluid applied for lubricating. The friction coefficient was figured out under different voltages. Through the microscopy, we can read,the wear scar diameter ,and analyze the results.
