摘要
Abstract
Nano-carbon balls cutting fluid was applied to the cutting processes of difficult-to-ma-chine aerospace gear steels(15Cr14Co12Mo5Ni2W),and the lubrication enhancement effects of nano-carbon particles on the cutting fluid were investigated.Firstly,a cutting force model for metal cutting was established to analyze the relationship between cutting lubrication and cutting forces.Further-more,through combined friction-wear tests and milling experiments,the lubrication performance of nano-carbon balls cutting fluid was evaluated in terms of friction coefficient,wear volume,friction surface quality,and cutting forces.Compared with the base cutting fluid,when the mass fraction of nano-carbon is reached 0.02％,the milling forces for the gear steels are decreased by over 10％,and surface roughness is reduced by more than 15％.Experimental observations reveal that nano-carbon particles on the friction contact surfaces preferentially are adsorbed onto micro-peak regions with high-er surface free energy,forming a nano-carbon adsorption film.Lubrication mechanism analysis indi-cates that this adsorption film may exert a friction-reducing"micro-bearing"effects.关键词
