Abstract

The possibility of usage of electrosensitive lubricant in the transition processes at interaction of junctions with oxide-ceramic coatings is investigated. This lubricant allows changing the coefficient of sliding friction and provides effective governing of tribotechnical characteristics of rubbing junctions due to controlled change of rheological properties of a lubricant in elastic hydrodynamic contact. The contents of lubricants are developed and their viscoplastic properties at changing such factors as applied electric field, the type of composition components are investigated. The sliding friction coefficients are evaluated.
