Abstract
The 35 steel dry friction and oil lubrication conditions, and under different loads sliding friction test, friction and wear properties and analysis of wear mechanisms by 34GrNi2Mo steel with soft nitride. Results show that the friction coefficient and wear amount of dry friction to be significantly higher than the oil lubrication of the friction coefficient and the wear amount in the two kinds of conditions of the dry friction with oil lubrication, the average coefficient of friction with the increase of the load increase, dry friction surface is very rough, more obvious groove-shaped wear scar and hard particles shed residual pits; in oil lubrication friction conditions, the friction surface of convex particles are polished not ditch like wear scar and residual pits after the falling of the hard particles, the surface is very smooth.
