Description

technical field [0001] The invention relates to a micro-nano friction test method and device under the condition of an applied potential, in particular to an electronically controlled friction method and device for a micro-nano textured surface. Background technique [0002] The traditional friction control technology is mainly realized through the reasonable compatibility and lubrication of friction pair materials. The disadvantage of these methods is that they cannot change the friction coefficient in real time and online under the actual working condition of the friction pair. In recent years, some researchers at home and abroad are exploring the use of electricity, magnetism, ultrasonic waves, etc. to affect the friction behavior of friction pairs. The use of electric field to control the process of friction and wear originated in the 1950s, the use of magnetic field control technology originated in the research of Indian scholars in 1968, and the use of ultrasonic acti...

The disadvantage of these methods is that the friction coefficient cannot be changed in real time and online under the actual working condition of the friction pair.

However, the existing friction and wear test equipment, such as pin-on-disk friction and wear testing machine and four-ball friction and wear testing machine, are not suitable for tribological testing of micro-nano textured surfaces, nor can they actively control the tribological properties
