摘要
以一种铁磁流体和添加剂为润滑介质，研究了ＧＣｒ１５ 钢销－盘摩擦副在边界润滑状态下受外加电场作用后摩擦系数的变化情况，并对试验结果和电场作用机理进行分析．结果表明：不同方向的直流电场导致摩擦系数的不同变化趋势，其最大变化率达３５％ ，且试验数据稳定，变化过程可逆．
With a ferromagnetic flow added with an additive as lubricant, the variation of friction coefficient between GCr15 (SAE 52100) steel frictional pair in a pin on disk tribometer under boundary lubrication in the presence of applied electric field was investigated. The result was discussed and the action mechanism of applied electric field on friction coefficient was analyzed. It has been found that the friction coefficient can be changed up to 35 percent with the applied direct current in different directions when ferromagnetic flow was used. The stable friction coefficient data and reversible change of friction coefficient were obtained, thus, ferromagnetic flow is of unique function on the active control of friction coefficient by externally applying electric field.
