Robust lubricious and low corrosive imidazolium hexafluorophosphate lubricant on multi-arc ion plating Ag-Cu/Ti film under sliding electrical contact

Ultrasonic-assisted top-down preparation of NbSe2 micro/nanoparticles and hybrid material as solid lubricant for sliding electrical contact

“…(1) mechanical exfoliation by tape, and (2) ultrasonic-assisted exfoliation in organic solvent. Ethanol is selected in this study because it is also a good solvent commonly used in drop-casting process [4] , [5] , [6] , [21] .…”

“…A copper pin (3 mm in diameter and 15 mm in length with a hemispherical tip of 3 mm) sliding on a copper disk (25 mm in diameter and 3 mm in thickness) are used. Experimental details can be found elsewhere [21] . Test conditions are: 0.76 mm/s for sliding speed, 3 N for normal load, 20–25 °C for room temperature.…”

“…In specific, clean metal sample is coated with liquid lubricant by applying dilute lubricant solutions in a volatile carrier, e.g. 1,1,1-trichloroethane, ethanol [21] . Likewise, the as-received NbSe 2 micro/nanoparticles in organic solvent (e.g.…”

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.…”
