The Voltage-controlled Tribological Characteristics of One Kind of Aqueous Cutting Fluid In this study it has been shown that the electrode potential of the metal side of a metal/ ceramic sliding couple determines whether friction coefficient increases or not. 一种水基切削液的电控摩擦性能不同的金属材料对应不同的电极电势区间,也即产生电控摩擦所需临界电压不同。
