文摘
Lubrication is one of the most important methods for maintaining and improving the reliability of electric contact components. In view of the conductivity, the lubrication performances of ionic liquids under electric contact have been investigated by using a reciprocating sliding tribometer. Compared with dry friction condition, ionic liquids present an excellent lubrication property. Meanwhile, under the low-load condition, the contact resistance as well as electrical power consumption decreased obviously when lubricated with ionic liquids. And the stronger current strength it is, the higher coefficient and lower contact resistance it shows. The reason could be ascribed to the current-induced fracture of the ion-adsorbed film, especially those in the asperities. And the transformation of the direct contacts, in turn, affects the friction coefficient and contact resistance.
