The Tribological Characteristics of Polyimide Bonded Solid Lubricating Films under Different Lubrication Conditions

Abstract:

In this paper, the tribological behaviors of polyimide bonded PTFE solid lubricating film and polyimide bonded MoS2 solid lubricating film under dry sliding and under lubrication of kerosene oil, diesel fuel, paraffin liquid and lubrication oil were investigated by using a ring-on-block wear tester. The results show that the anti-friction and wear-resistance properties of both lubricating films are greatly improved under oil lubrication conditions as compared with the dry friction condition; the friction coefficients of both lubricating films under different oil lubrications keep steady-state value with 0.08; but both lubricating films under different oil lubrications reveal the different wear-resistance properties, such as the best wear-resistance properties under diesel fuel, followed by paraffin liquid, lubrication oil and kerosene oil; the differences in the wear-resistance properties of the lubricating films under different lubrication conditions are mainly ascribed to the influence of the oil’s characteristics, especially boiling point and viscosity.
