However, the current electrorheological fluid is a suspension system formed by dispersing easily polarized dielectric particles with high dielectric constant and low conductance in insulating oil with low dielectric constant. The electrorheological fluid mainly polarizes dielectric particles through changes in the electric field. , thereby changing the viscosity of the liquid, the performance of the existing electrorheological liquid has not met the practical requirements

Abstract
The invention provides a method for changing extreme pressure property between interfaces and a device thereof. According to the method for changing extreme pressure property between interfaces, an electric field is applied between two interfaces containing a lubricant. The lubricant contains a polar additive capable of changing extreme pressure property of the lubricant when voltage of the electric field changes. By the method and the device, extreme pressure property between interfaces can be changed. For example, extreme pressure property can be raised or reduced. Reliability of equipment is enhanced, and lubricating property requirement of equipment under different working conditions is met.
Description
technical field [0001] The invention relates to a method and a device for changing the extreme pressure performance between interfaces, in particular to a method and a device suitable for changing the extreme pressure performance of the metal interface of a gearbox and a guide rail. Background technique [0002] With the development of science and technology, various electromechanical systems are gradually upgraded. In the past, lubricants with different anti-extreme pressure properties were required to be added to different electromechanical systems, so that multiple lubricants existed in a complete system at the same time, such as engine oil, automotive gear oil, brake oil, transmission oil, etc. fluid and automotive grease. The generalization of lubricants is a matter of interest to those skilled in the art. [0003] Since the 1950s, people have carried out a lot of research on the relationship between the electric field and the tribological behavior of materials, and t...
