Ionic liquids are expected as lubricants under vacuum condition, because of low vapor pressure. We carried out a high vacuum pin-on-disc sliding tester to find out fundamental tribological properties of ionic liquids. Residual gases pressure was measured by using Q-mass analyzer during the sliding. Two ionic liquids (N,N,N-Trymethyl-N-propylammonium bis (trifluoromethanesulfonyl)imide and N-Methyl-N-propylpiperidinium bis (trifluoromethanesulfonyl) imide) and three pairs of pin/disc material (SUS304/SUS304, Al/SiC, Cu/SiC) were used. The ionic liquids demonstrated low friction coefficients for the sliding materials. During the sliding, the ionic liquid was decomposed and some types of gases were generated by tribochemical reaction, which behavior depended on the sliding materials.
