Abstract
ABSTRACTThe ILs ([Li (synthetic esters)] NTF2) were prepared by the in situ synthesis method. The tribological behaviour of the ILs to friction pairs of Ti‐6Al‐4V titanium alloy against silicon nitride was studied by SRV‐V under different concentrations and friction frequencies; the wear scar was studied by SEM, XPS and TOF‐SIMS. The results showed that the friction coefficient and wear loss decreased gradually with the increase of the LiNTF2 content; when the LiNTF2 content reached a certain value (10%), the friction coefficient and wear loss did not change much. Tribofilm composed of titanium oxide, Al2O3, TiFO2, AlOF2, Ti2O4F and Al2O3F plays a major role in lubrication and anti‐friction effect.
