Ball-on-plate sliding friction experiments were designed and performed to show the possibility of local friction control by electrochemical methods. By partitioning a metal plate into charged and uncharged zones, the friction coefficient in these zones can be differential when an external voltage is applied during rubbing. It is also possible to achieve differential friction at different locations...
Abtract A phenomenological model of the dependence of friction coefficient on external voltage is proposed based on experimental results of friction and electric current of three different tri-bopairs, Si3N4-ball/steel-disc, Si3N4-ball/brass-disc and SiO2-ball/steel-disc, lubricated with zinc strearate suspension. It was found that the variation of friction coefficient correlates with the variation...
