Electric arc-induced damage on electroless Ag film using ionic liquid as a lubricant under sliding electrical contact

Effect of Modified Nano Graphite on Conductivity and Lubrication of Environment-Friendly Lithium Grease

“…After modi cation by the ionic liquid, C-H bond stretching vibration peaks on side chain groups appear at 2931 cm -1 and 2860 cm -1 of the powder material, and the stretching vibration peaks of imidazole ring skeleton are correlated with the peaks at 1575 cm -1 and 1467 cm -1 , respectively. 1168cm -1 is the in-plane bending vibration peak of C-H, and the characteristic peak located at 841cm -1 belongs to the P-F bond stretching vibration of anions in ionic liquid [34]. The above peak values indicate that the nano-Graphite material modi ed by ionic liquid has been successfully prepared.…”

“…According to the literature, curve tting of Cu [PF6] [36]. In Figure 11(e), the peak of 530.6e V in the O 1s spectrum belongs to metal oxide [34,35], the peak of 531.5 eV and 532 eV May be C-O peak and C=O peak, and the peak of 532.5eV belongs to Cu 3 (PO 4 ) 2 [35]. Two distinct peaks were observed in the F 1s spectrum: the peak at 686.5 eV indicates that a C-F bond may be formed on the surface of the copper block, while the peak at 688.4eV indicates that the worn surface contains [C14MIm][PF6] [35,36].…”

Mechanism of Multilayer Graphene/Ionic Liquid Synergistic Regulation of Interface State under Current‐Carrying Friction

“…In recent years, to optimize the performance of conductive greases, two main strategies have been used in the literature: 1) replacing the grease main body with better conductivity and 2) adding conductive additives. [14][15][16][17][18][19][20][21][22][23] A typical example of the first strategy is conductive grease with an ionic liquid (IL) additive. IL can form a chemical adsorption film on the friction interface, providing protection.…”

“…[18,[24][25][26][27][28] Additionally, IL has excellent electrical conductivity, allowing these conductive greases to exhibit excellent tribological properties and low contact resistance. [14][15][16][17][18][19] However, IL is expensive, and the contact surface may corrode. [16,[29][30][31] The typical design of the second strategy adds conductive particles with high electrical conductivity to the lubricant, such as Ag, Cu, Pd, Sb, Sn, or other metal particles.…”
