Problems solved by technology

[0002] The pursuit of low friction or even zero friction has always been a hot topic in tribology research. As a typical anti-friction coating material, carbon materials have high hardness, low friction coefficient, and high wear resistance. The friction coefficient can be as low as 0.01~0.1, and the surface that usually rubs against carbon materials is a surface with less roughness, such as ceramics; but for metal surfaces, the friction coefficient is difficult to reach a very low friction stage

Abstract

The invention discloses an applied electric field-induced friction device and a testing method thereof. The applied electric field-induced friction device comprises a pedestal, an upper friction pairscomposed of a conductive clamp and a metal friction piece arranged at the bottom of the conductive clamp, a lower friction pairs composed of a carbon based film and a plate electrode arranged at thebottom of the carbon based film, and a motion unit and an adjusting unit arranged at the pedestal, a strain beam, a loading unit, a cantilever beam, and a power source which are arranged at the pedestal. The motion unit pushes the lower friction pairs to move, a strain sheet is arranged at the strain beam, the front bottom of the cantilever beam is connected with the upper friction pairs, the topof the front end of the cantilever beam is connected with the loading unit, the rear end of the cantilever beam is connected with the front end of the strain beam, the adjusting unit is connected withthe rear end of the strain beam, the position of the upper friction pairs is adjusted, a positive pole of the power source is electrically connected with the conductive clamp, a negative pole of thepower source is electrically connected with a plate electrode, so that the friction coefficient between the metal friction piece and the carbon based film is reduced.

Description

technical field [0001] The invention relates to the technical field of friction devices, in particular to a friction device induced by an external electric field and a testing method thereof. Background technique [0002] The pursuit of low friction or even zero friction has always been a hot topic in tribology research. As a typical anti-friction coating material, carbon materials have high hardness, low friction coefficient, and high wear resistance. The friction coefficient can be as low as 0.01~0.1, and the surface that usually rubs against carbon materials is a surface with less roughness, such as ceramics; but for metal surfaces, the friction coefficient is difficult to reach a very low friction stage. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a friction device induced by an external electric field and a testing method thereo...
