对（Ｃｕ－４３Ｎｉ）／Ｃｒ，（Ｃｕ－４３Ｎｉ）／ＴｉＮ和（Ｃｕ－４３Ｎｉ）／ＮｉＰ这３种摩擦副摩擦产生的热电势信号作了频谱分析，并对三者进行了施加不同特性的交变电势信号的摩擦试验．结果表明，将交变电势施加于３种摩擦副均可降低摩擦力，降低程度与所加电势的幅值、波形及频率特性有关．
The thermoelectric power signals generated by the friction of Cu-43Ni / Cr, (Cu-43Ni) / TiN and (Cu-43Ni) / NiP were analyzed by frequency spectrum and the three were subjected to different characteristics Friction test of alternating potential signals. The results show that the application of alternating potential to the three kinds of friction pairs can reduce the friction force, and the degree of reduction is related to the amplitude, waveform and frequency characteristics of the applied potential.
