摘要
通过试验研究了处于边界润滑状态下钢钢摩擦副在铁磁流体及加有添加剂的铁磁流体中的摩擦特性，特别是在电场作用下摩擦系数的变化情况．在销盘试验机上进行的试验表明：加有添加剂的铁磁流体在不同方向的直流电流作用下，其摩擦系数变化的幅度最大可达到２３％ ．因此得到了一种在边界润滑状态下摩擦系数可控的新型润滑介质．这样就可能通过外加电场的手段实现摩擦系数的主动控制，达到减摩。
The frictional performance of steel on steel frictional pair under boundary lubrication with ferromagnetic flow added with additive and their friction coefficient by the action of applied electric fields are studied .The experimental results from the pin on disk tester show that the friction coefficient of ferromagnetic flow added with an additive can be changed by 23 percent by the action of oppositely directed applied direct currents ,so a new type of lubricating agent with controllable friction coefficient under boundary lubrication is obtained. It is possible to control friction coefficient actively with applied electric fields in order to reduce friction and energy loss.
