Abstract
Electrochemical kinetic techniques are widely used for studying redox processes in aqueous solutions and in recent years have begun to be applied in non-polar solvents. This paper describes the application of such techniques to investigate lubricant additive reactions in solution in lubricating oils. The main practical difficulty is the low electrical conductivity of most liquid lubricants. A number of different approaches have been employed to try to overcome this problem, including the use of microelectrodes, of supporting electrolytes to enhance the conductivity of lubricants, and also the use of a scanning tunneling microscope (STM) system, with a Pt-Ir STM tip as the working electrode separated by nanometer scale gaps from a Pt substrate as reference-counter electrode.
