Research on the tribological characteristics of magnetic porous surface with magnetic fluids parameters and its operating conditions

Abstract

The magnetic fluids lubrication specimen with magnetic porous surface is prepared and its tribological tests are carried out in this paper. The tribological characteristics of the specimen under different load, velocity and magnetic fluids parameters were investigated. The results show that the friction coefficient decreases with the increase of rotation speed under all load conditions and its anti-friction effect increases as the rotation speed increases; On the other hand, the friction coefficient decreases with the increase of the load under all rotating speed conditions. The saturation magnetization and liquid viscosity exists the best anti-friction effect that can be obtained such as magnetic fluids with the saturation magnetization of 200 KA/m and the viscosity of 30-34mPa.s in the paper.
