Abstract: Under boundary lubrication with bearing steel and brass as friction pair, the performance of controlled friction of some common and special lubricating materials under the application of electric field is studied. Result shows that the friction coefficient of these lubricants can be changed remarkably by the externally applied electric field, but only a type of ferromagnetic flow, called BH-1.exhibits better performance on the friction control. It also suggested that the controllable property of friction was not general for every lubricant.
