摘要
The effect of magnetic fteld on the tribological process of sleeve-ring pair lubricated by WRL lu-bricants was investigated by means of a NG-x wear tester and a PS5013 video microscope. The friction coefficient (f) and the wear weight(W) in lubricating test with WRL lubricant were decreased with the increase in the ,mag-netic field vertical to the rubbing surface, and an almost zero wear lubricating situation was gained in a magneticfield of 1000A/m. The captured wear micro particles on the rubbing surface were observed in the testing process,and the theoretical analysis of magnetic effects was completed. It is indicated that the magnetic field has not only a capturing action of wear micro particles on the worn surface, but also a inducing polarization0 of magnetic anisotropy of lubricant molecular. The actions promote the absorption of WRL lubricant into the wear swrface aswell as wear micro-particles, so that a good tribological effect is obtained when both magnetic field and WRL pr-esent.
