Molybdenum dialkyldithiocarbamate(MoDTC)is widely used as a friction modifier in engine lubricating *** MoDTC lubrication,the friction and wear behaviors of tungsten-doped diamond-like carbon(W-DLC)films annealed at 100-400℃were discussed and evaluated using scanning electron microscopy(SEM),atomic force microscopy(AFM),and Raman ***(polymerized alpha olefin)PAO+MoDTC lubrication,the coefficient of friction of all samples decreased,but the wear rates of the W-DLC films annealed at 300℃increased *** interacting with zinc dialkyldithiophosphate(ZDDP),the wear rates of W-DLC films annealed at different temperatures declined significantly owing to the formation of dense phosphate tribofilms on the worn surfaces.

In order to improve the surface hardness and wear resistance of aluminum alloys,nitrogen ions were implanted into LY12CZ aluminum alloy by plasma immersion ion implantation （PIII） *** chemical states,surface hardness,composition distributions,tribological properties,and anti-corrosion behaviors of the N-PIII coupons in 3.5% NaCl saturated aqueous solution were investigated.X-ray photoelectron spectroscopy （XPS） analysis indicates that the modified layer is mainly composed of AlN phase and a fraction of Al 2 O 3 *** depth profile of implanted nitrogen ion has two peaks,corresponding to 40nm and 88nm from the surface,*** surface hardness is obviously improved by dispersion strengthening from AlN phase,and the maximum value increases by 140%.friction and wear behaviors of all these samples exhibits that the friction coefficient reduces from 0.47 to *** with the untreated substrate,the anode polarization curves reveal that the corrosion potential （E corr） of all implanted samples increase and corrosion current density （I corr） decrease,the maximum E corr increases by 200mV and the minimum I corr decreases by over two orders of *** also indicates that the wear tracks of modified coupons are much shallower and narrower than that of untreated sample,the minimum wear loss decreases by 43.4%.Tribological property and corrosion resistance of aluminum alloys strongly depended on the composition depth profiles of the modified layers.
